Modified default.pa as above and it works.
I now get 2 pulse sink and 2 pulse source, but nothing connected.

I'm pretty sure the behavior has been the same all along. Did some
googling, and found that there in deed is an option for stopping the
sink and source from auto-connecting, by adding the option:
connect=false
http://lists.freedesktop.org/archives/pulseaudio-discuss/2007-July/000420.html

So, if you want to have the sink and source loaded automatically, but
not auto-connect, change the line in /etc/pulse/default.pa to:

load-module module-jackdbus-detect channels=2 connect=false

Or, if loading sink and source manually:

pactl load-module module-jack-sink channels=2 connect=false
pactl load-module module-jack-source channels=2 connect=false

(I think) Previously (AV Linux & UBS 12) the Pulse sink and source was
there but not connected.
Then my script connected them where I wanted them to go. The script still
does this, but
the pulse output is already connected to the AF12 ch1 & 2 and then my
script connects them
to ch1 & 2 again. So I want Pulse source & sink, I just don't want it to be
auto connected.

It might be a couple days before I get to actually work on this again.

You'll need to restart pulseaudio (as you suspected) to have changes
take effect. Just do: pulseaudio -k

I think in order to not have the sink and source autoconnect, the code
will need to be changed, or perhaps there is an option for that (like
channels=2).

To load the sink and source manually (not using dbus-detect), do:

pactl load-module module-jack-sink channels=
pactl load-module module-jack-source channels=

Well I did try commenting that out. But, the connect didn't go away...but,
I didn't restart pulse either.

Also, I want the Pulse channels, I just don't want them auto connected; I
want to control the connection in my script.

One difference should be that before PA would autoconnect to all the
outputs of the audio IF. Now, it only connects to two by default.
In /etc/pulse/default.pa:

load-module module-jackdbus-detect channels=2

If you'd rather not have the sink and source loaded by default (and
automatically connect), you can just comment out that whole section,
like so:

# .ifexists module-jackdbus-detect.so
# .nofail
# load-module module-jackdbus-detect channels=2
# .fail
# .endif

[ubuntu-studio-users] Pulse and Jack

[Mac]

I have a script that does a bunch of connections when I start Jack via
Qjackctl.

It connects various things like calf plugins, zita meters/xovers, etc. and
my AF12 into a tri-amp system.

I figured this out under AV Studio, then moved it to UDS 12.04.

The other day I built a system with UBS 14.04.

The script still works, but...

By default when Qjackctl starts jack it auto-magically connects the Pulse
output to the first two channels on my AF12.

Then my script adds my desired connections, except I don't want to two
connections mentioned above.

I don't remember if I actually figured out how to stop the connection
previously.
Or, if it does it differently in 14.04

In any case I have also not been able to find enough info on the web to get
me to the point where I can even find where the auto-magic connection is
happening (and thus figure out how to stop it).

Help an addled old mind. Thanks. ;)

its not a safety issue in any way. if i didnt want pulse, i would just
remove it, but there is really no reason to remove it, unless you just
prefer not having it, and if i were a person who wanted to not have pulse,
i would start with lubuntu, which doesnt ship pulse (AFAIK) and add what
packages i want, such as JACK and ardour... the "best" way will always be a
matter of preference and use case. if you dont want pulse, remove it, but i
would consider troubleshooting the issues you are having. JACK can be setup
not to use the pulse dbus, if you want JACK only... in the qjackctl gui
under the "misc" tab, untick dbus

sounds like you are trying to troubleshoot many things i once. i would try
and isolate a few things. try using whatever mixer controls you want with
the internal audio device only, and wait til you get sound working and you
understand the tools a bit better before moving on to even plugging in the
Komplete USB device.

[ubuntu-studio-users] Pulse Audio? Where is alsamixer?

[Henry W. Peters]

Alright, got Ubuntu Studio 13.10 installed on my ext. usb drive, on my 
HP Pavillion desktop, now trying to configure for functionality.


Wondering, first of all, if Pulse audio can be safely turned off...?  & 
if so, what is the best way to do this?


Second, though alsa appears to be installed, when I call up 'alsamixer' 
from terminal... I get:


"cannot open mixer: No such file or directory"

I installed a gui alsa mixer (gnome alsamixer)... but it crashes after I 
start it


Third, having trouble getting sound IN from my Native Instruments 
Komplete Audio 6 usb 3.0 device... (presently, using s/pidf connect from 
my Yamaha 01v mixer). I can get sound from /in/ the CPU, i.e., radio 
streams, audio cd's, etc.. & I figured out how to get midi IN & OUT... 
so any one with such experience, & insite, your suggestions would be 
more than welcome.


Thanks,
Henry

On 12.x when jack is started by qjackctrl, the local pulse audio
devices show up as sources and sinks.

I have not dug around and figured that out in depth. That's on my todo  
list.




pulseaudio-module-jack is what does it. It's possible to have PA create  
sink and source for jack manually too, but the module does it  
automatically, whenever you start jackdbus (qjackctl is set to start  
jackdbus by default (Setup -> Misc -> Enable D-Bus Interface).




In my case I also have an AF12 plugged into the firewire port, so in
addition to the pulse sinks/sources, 12 sinks and sources show up as
well.


Think of the PA sink and source as an application connecting to jack.



In addition, I have some scripts that execute when qjack starts that
add and patch some other apps.

If I boot the pc and start qjack, then start a browser with audio
content, it comes through the PA source and goes to the rest. This
works just fine most of the time.

There two situations that cause me some grief:

1.) If I start the browser content, then start qjackctrl, from that
point on no audio from the jack side of the house. (The PA side still
shows, in volume control that it's getting to PA.) I can avoid this by
having a better memory and remembering to start qjack.


There are one or more bugs causing the exchange between PA and jack not  
work flawlessly, as of yet.




2.) If for some reason the stream from the browser dies, for example a
video goes into buffering for too long, the browser and jack appear to
be hung. (I've seen ffado go south in this case and I don't know how
to recover it live either.) In this case, my memory won't help...can't
predict network sluggishness.

In both situations, I've found no way to recover short of reboot.

Is there a way to recover in either case?


Try killing jack with: killall -9 jackdbus

If that doesn't help, make sure to kill jack and also restart PA, by  
killing it.

Mac

Getting online is "risky" regardless of the browser in use.. the facts are,
if you want current flash, chrome is providing it. Chrome is not supplied
in ubuntu (and likely other distros) because of licensing issues with
things such as flash. My favorites are not mentioned here, since that is
irrelevant.

Correct!

For some usage HTML5 might replace flash, but as far as I know only
Chrome is able to do everything or at least most of the things flash is
needed for.

No reason for a flame war. I wish distros would provide more Chrome
instead of Chromium. The issue for me isn't a policy, but I prefer
browsers providing another GUI, IOW a different workflow.

My favorite still is Firefox, followed by Opera, but current versions of
Opera already follow this Windows8-Unity-TabletPC style.

OT: The homepage of my provider already is unusable for me. There were
always issues when using Linux, but now not only Linux does cause
issues, but I'm unable to even find the location to download the bill.
It's an idiotic design, similar to Unity, much more evil than iOS.
There's no chance anymore to simply click something and to reach the
download link for the bill's PDF. Animated icons, an insane chaos.

The modern DE design has influences to the web design, it's a PITA. It
clearly does show that most people not really use the computer as a
tool, it seems to be a toy for most users.

you can read there..

" (Flash Player 11.2 is the last supported Flash Player version for Linux.
Adobe will continue to provide security updates.) "

what do i do? i run the chrome browser in 32bit linux.. chrome gets its own
flash.. again from the link..

" Chrome (Pepper-based Flash Player) 11.6.602.167 "

please, no comments or flames about chrome.. im not saying you should use
it, or that it is "good" or "better".. just stating the fact that if you
want current flash, chrome is providing that in linux, and from what i
read, that is 32bit chrome only.

i havent *ever* had issue with flash audio in ubuntu, ubuntustudio,,
pulseaudio, alsa only... cheers!

In the past I've toyed with the gstreamer solution. Works ok for one
audio play. For example, when the song starts the divice shows up in
qjack and can be patched to output. But, when the song ends, the
device goes away and a new device appears for the next song. This
appeared to be the default way most apps were using gstreamer to jack.
I found no way around this behavior.

This is also an issue without PA. I often used distros that fixed it by
default, today I don't care about this issue. It's possible to get rid
of the problem, but I don't know how, perhaps just following the flash
and gstreamer instruction does help: http://jackaudio.org/faq

However, at least flash won't work anymore for Linux in the near
future ;).

IIRC I once edited gstreamer, perhaps the method was a little bit
different, than it is described by the current FAQs.

On 12.x when jack is started by qjackctrl, the local pulse audio
devices show up as sources and sinks.

I have not dug around and figured that out in depth. That's on my todo list.

In my case I also have an AF12 plugged into the firewire port, so in
addition to the pulse sinks/sources, 12 sinks and sources show up as
well.

In addition, I have some scripts that execute when qjack starts that
add and patch some other apps.

If I boot the pc and start qjack, then start a browser with audio
content, it comes through the PA source and goes to the rest. This
works just fine most of the time.

There two situations that cause me some grief:

1.) If I start the browser content, then start qjackctrl, from that
point on no audio from the jack side of the house. (The PA side still
shows, in volume control that it's getting to PA.) I can avoid this by
having a better memory and remembering to start qjack.

2.) If for some reason the stream from the browser dies, for example a
video goes into buffering for too long, the browser and jack appear to
be hung. (I've seen ffado go south in this case and I don't know how
to recover it live either.) In this case, my memory won't help...can't
predict network sluggishness.

In both situations, I've found no way to recover short of reboot.

Is there a way to recover in either case?

Regards,
Mac

This is the way it works on Ubuntu Studio, by default, but if you are
looking to do this manually, you might be better off looking at other
sources.

I don't know how it works (as I've never needed to). Found this
https://wiki.archlinux.org/index.php/PulseAudio/Examples#PulseAudio_through_JACK_the_new_new_way.
Hope it gives some insight.

I spent some time last evening looking at a variety of links on the
web and looking through scripts in the /etc/pulse directory and others
and was not able to connect the dots.

I will get the source for pulse and have a look at that. But, I
suspect that will clarify how pulse itself works, I'm not sure if it
will help me with the how the whole thing gets lashed together.

For instance, I found no specific in any of the scripts I looked at
that indicated how, when the qjackctl Start button is clicked, the
Pulse_sink/sources that appear (in my case, left/right front/rear, lf,
aux1/2/3 front/rear, etc.) are specified. And why they are there, but,
the mic in front/rear don't show up. Also, how all 12 ins/outs of the
firewire device also show up, but the qjackctl setup calls this out,
so I'm not surprised it is there.

Actually, I have no feelings either way. When I started using Ubuntu
back at 8.x pulse combined with alsa seemed to be the source of lots
of issues.

When I installed UBStudio12.04 and the pulse sources/sinks just showed
up (along with my firewire devices) and just worked (with no
intervention by me) I was fine with that.

In fact, I never understood, why one would not want all the devices on
the PC to be available for connection in jack. For instance, if I have
12 chans of I/O on a firewire device, two mic inputs on the mobo, 5
chans of ouput on the mobo, and 2 chans of I/O on a usb device, why
wouldn't I want them to show up in jack?

I may never want to use the mobo mic input, but, I'd rather just
choose not to, rather than having to rip out this, that, and the other
thing before I can get to where I can add the mobo mic inputs.

The OP seems to like pulseaudio, however, if he shouldn't need it, I
recommend to remove it. I removed pulseaudio from Precise and Quantal.

Re: pulse audio & jack

[Josep Pujadas i Jubany]

You need to stop/start/stop PulseAudio when using JACK.

http://translate.google.com/translate?hl=en&sl=ca&tl=en&u=http%3A%2F%2Fwww.bellera.cat%2Fjosep%2Fumm%2Fconfiguraci_de_jack.html

Like this if you have applications only compiled for using with PulseAudio
they will work also with JACK.

Be careful with que scripts code. One of them is "Language system sensitive.

Tested/proved for Ubuntu Desktop 10.04 and also for 12.04.

The way it's automatically done, is by the combination of qjackctl using  
dbus support with jackd2 (i.e. starting jackdbus), and having  
pulseaudio-module-jack installed.

You can check out the source for pulseaudio-module-jack for specifics.


Or, can anyone post some ideas on where to start? (I googled a bit

On a related note: if I run/start qjackctl things work fine. If I then
tell qjackctl to stop and choose yes/continue when it prompts about
clients still connected it can't connect when I attempt to start it
again. The message says it can't connect(or start) to the server.

I'm guessing there are stale processes that are not allowing the
restart, but, I'm not real sure where to begin to determine how to
correctly stop jack so it doesn't get it's knickers in twist.



This is a bug, that hopefully will be fixed in both 12.04 and 12.10 soon.

Perhaps a DBUS thingy? If you start qjackctl, it will launch the script
in /usr/bin, this script will turn off pulseaudio and than run
qjackctl.real, the actually/real qjackctl. So when using qjackctl,
pulseaudio shouldn't cause issues. DBUS might cause issues.

i like it... so does anyone plan on taking out, or disabling the internal

0. Ubuntu's default sound system is PulseAudio and ALSA. If you can
connect PulseAudio to JACK, you can use JACK and FFADO like default
sound system.

1. Then firewire sound device user can use web services like ustream,
youtube (with flash script) or pulseaudio applications like skype.

2. So You can use the sounds from JACK application for ustream or skype.

3. And You can utilize PulseAudio's networking with JACK.

have any useful ideas, guys?

Re: Pulse Audio and Jack in Maverick

[Takashi Sakamoto]

You can see this integration on http://ubuntustudio.org/LucidLynx as
"Pulse Audio built against Jack is available".

This integration is for lucid or later because "pulseaudio-module-jack"
package is not released for karmic or latter refering to this URL,
http://packages.ubuntu.com/lucid/pulseaudio-module-jack

I'm a Japanese user of Ubuntu Studio and make some documents in Japanese
community. Last week I make a document about this PulseAudio integration.

https://wiki.ubuntulinux.jp/UbuntuStudioTips/Application/JACK-PulseAudio

In this document. I suggest to use qjackctl option "Execute script after
Setup" instead of config file. If you check this option and input two
commands, you can get "PulseAudio against JACK", load this module just
after JACK runnning.

If you are interested, read it with web translation service like google
or yahoo with plain text.

JACK/Pulse Audio Integration in Maverick

[Scott Lavender]

Greetings,

I did some testing of the JACK and Pulse Audio integration with D-BUS in
Maverick along with some of what was required to arrive at that juncture.

For those who are curious you can read about it at:
http://dullass.blogspot.com/

I hope you enjoy it.

Re: disabling pulse audio in 9.10?

Hi, Iain!

I tried both way simultaneously, so can't affirm for certain, but,
yes, I believe that xfce is not using pulseadio. May be somebody
correct me.

Thanks, I was going to switch to xfce actually, thought I'll keep gnome on
there too for ohter purposes. Does the pulse daemon just plain not get used
by xfce?

Re: disabling pulse audio in 9.10?

[Oleg Ivanenko]

Hi, Iain!

My setup

1. Switch off /apps/gnome_settings_daemon/plugins/sound/active in gconf-editor

2. Switch off Gnome sounding at all in gnome-volume-control(I believe so)

3. Create file ~/.pulse/client.conf consists of
autospawn=no

4. killall -KILL pulseaudio

5. start jackd with qjackctl

Alternative way: install xubuntu over ubuntustudio and use xfce
instead Gnome :)))

I use this : http://www.sandgreen.dk/index.php?side=python_uat to remove 
Pulse completely. It's a work in progress but it works for me (YMMV).

If you have any problems, please let me know so I can improve it.

disabling pulse audio in 9.10?

[Iain Duncan]

Hey folks, wondering if anyone knows what would be different for disabling
pulseaudio for 9.10. I've managed to get it so it doesn't restart, following
these:

http://idyllictux.wordpress.com/2009/04/21/ubuntu-904-jaunty-keeping-the-beast-pulseaudio-at-bay/
http://ubuntuforums.org/showthread.php?t=1348604

But it's still running on startup even though I removed all the runlevels
using sysv-rc-conf

Not sure if I'm doing something wrong or the above are just out of date, any
help appreciated. I'd like it be a strictly jack on alsa setup.

Thanks!

There is a chance that we may have an RT kernel for jaunty. It may not be in 
the repositories, but I would like to at least make an RT kernel available to 
play with for PowerPC users, since we seem 
to have a few more around here these days, which IMO is great. :)

With the apps available today, I would say yes it is too slow. You'd probably 
want a minimum of a G4 1.42Ghz. A dual CPU G4 as low as 800MHz may work well 
enough if you were to use a minimal desktop 
environment, shut down unneeded services, etc.

Thanks for the link. I had a look at the video, but I'm still not sure 
where to start.
I also spent most of the day fiddling with Python/Glade and it seams 
approachable, and have even made my wineasio-script as a 
phyton-gui-thingie :-) (a work in progress).

I realy like to help out, but being new to this I'm a little lost, what 
do I do now... should I join the dev-list or just go to irc and find 
someone to ask for directions ?

_MMA_ is me on IRC. ;) And *generally* I agree. But is there's simple

Keeping packages up-to-date is probably our #1 request (with the whole
JACK/Pulse thing a close 1.5). We have a *little* more help now on the
packaging front but it would be great to get 1 more like Khashayar.

It should be noted that writing new programs (in C++, pascal, python,
lolcode, or any other language) probably isn't the best way to help
UbuntuStudio (keep in mind, I'm not a dev, but this is what I've been told
from MMA).  Packaging and maintaining packages is probably more benificial
to the project, and it's signifcantly less work than writing new programs.

Here's a nice Youtube tutorial for the beginner packager that I found very
helpful when starting out: http://www.youtube.com/watch?v=zKLabbXTqMc

Ok noob trying to get up to speed here - respond or not as patience

I looked up Pulse and it sounds great.  And it sounds like it doesn't  
work entirely - based on wikipedia and this thread.  In a nutshell  
(or a c shell, hardy har har - oh "hardy", there's another one, I  
kill myself...) what is possible with Pulse that is not possible  
without it?  Just trying to decide if I would really need it or not...

I have nothing but respect for UbuntuStudio, it has been my main os 
since Feisty. I try out other distros once in a while, just to learn 
something new, and none of them comes close to the level of perfection 
that UbuntuStudio has.

I wish I could do more to help, but theres a long way from making a 
simple script to actualy develop something usefull. I know a little 
Pascal, and have tried to learn things like C+, but my head hurts when I 
try to wrap my brain around it, even compiling a new kernel leaves me 
baffled :-)

As I mentioned before, I don't hate Pulse, I just cant use it in its 
current state, and althou it might be a "quick fix", I see a 
Pulse-on/off script/program as a temporarely solution so more will be 
able to use UbuntuStudio.

A "JACK" only Ubuntu Studio has certainly been thrown around. (and is
still not out of the realm of possibility) It's a much tougher decision
to make than you know. While music folk are for sure our largest user
base I have many emails from teachers/artists and the like talking about
using Studio. Mostly from the "I didn't know about these apps." standpoint.

*Countless* bugs and ML posts would ensue from people wondering "Why
doesn't app "X" work in Studio? It works in Ubuntu!" I'm just not ready

Pulse already shuts off so JACK can start now. As for the WINE part, I
have no clue. I don't use it.


In the end, there are *MANY* things that can be done so that things run
smoother for all. Even is they are done by the user later, we can make
it easier. Getting involved with Ubuntu Studio Controls
(https://launchpad.net/ubuntustudio-controls) is one place. Our
resources are so finite it's crazy. You guys just don't know how thin we
are stretched. For things to really get better we need more users to
turn developers. Nobody wants to hear it but it's true. I was one.
Khashayar is our most recent.

So we do what we can within a given release. Our only other alternative
is to board up shop. Close it down. And I feel that would be a shame as
the Ubuntu brand has brought alot of light to our corner of the world.
Shame to lose it.

This have improved *greatly* since the Feisty days. Progress is slower
than most would like but without the same resources as Canonical ,
Microsoft or Apple, it is what it is.

Jackd-support for pulse is only part of the problem, I have also had 
problems with wine/wineasio in a pulse enviroment. It might be a wine 
issue, but since it works with Alsa, that is what I use.

I can understand the reason not to make a non-pulse Ubustu dist, at 
least from a developers point of view, but as a mucissian who just want 
to make music, I need a stable working enviroment, and untill wine and 
jackd can "speak pulse", I defenitly think that the need for a simple 
script/program that can make the switch from pulse to Alsa (and back again).

Some time ago I made a wineasio-script and placed it on my website : 
http://www.sandgreen.dk/index.php?side=linux_wineasio
This month alone, it have been downloaded 726 times, so I know theres a 
need for simple solutions for those who doesnt want to copy paste 20 
lines of code one by one and fiddle with system preferences when they 
install a new system.
As my site also mentions "I am a musissian, NOT a programmer", so thou I 
might be able to make a bash-script and host it, I'm not sure that my 
way of doing it is the best way.
Someone resently told me that these simple three lines is enough :

% sudo apt-get purge pulseaudio
% asoundconf list (Names of available sound cards: M2496)
% asoundconf set-default-card M2496

Is that realy all ?
What about system sounds ?

Any input would be welcome, and please remember that I didnt start this 
thread to start a Pulse-Alsa war, I just want to make my life easy when 
I reinstall, and maybe help a fellow non-geek musissian.
Pulse might be the future for Linux audio, but I cant wait till then :-)

I couldn't agree more!  But unfortunately it depends on jack being in main -
which the UBS devs are working on.  If jackd isn't in main, then the pulse
and xinelib packages can't have libjack-dev as a build-dependency, and thus
no jackd-support without a manual compile by elite users.

Though I did manage to find this (for pulse):
https://code.launchpad.net/~adam-lofts/pulseaudio/hardy-jack
and this (for xine):
https://bugs.launchpad.net/ubuntu/+source/xine-lib/+bug/152487
...and you know what they say about squeaky wheels and grease!  It's
probably best to push for this through official development channels rather
than ranting on a users mailing list.

Sorry again: this time I tried to be ironic...

Now loud and everybody say after me:

Ubuntu should have jackd-support for pulse and xinelib to be installed

Because it is needed,
because it is easy to do,

I see the "it's simple, just compile this or that" for all kinds of things
in Linux land.

I submit that it is simple for those who are comfortable with compiling and
want to do so.

But, I don't think the majority of users ARE comfortable in that realm and
for them it just isn't simple...if it was the forums would be way smaller.

And it could be argued that they will create more headaches for themselves
if they just live with it until it is available with a few clicks from a
repository.

The same with xinelib - install jack-dev, then compile xinelib from
source and amarok plays sound via jackd the same as xine/gxine etc...

It would be nice though, if we could get the needed plugins from

Well, I chased this a bit and was led to believe there is something called
alsa_in and alsa_out included with Jack 119.

These programs, again as I understand, when run from the terminal window
create an alsa sink or source that should show up in jack.

The back port came a few days after I attempted to compile Jack 119 on my
UBS hardy install.

The result was a jack that was no longer stable. And, no executable being
present for alsa_in/out. They are in the tools folder created from the jack
tar ball, configure/make script appear to do a recursive, and no apparant
errors in the build log files.

So, since the back ports for Jack, Ardour, and ffado are now available I am
planning on re-doing things later this week and hoping for better results.

Cory is correct: he never mentioned the core-devs - I made a possibly
misleading interpolation sorry for that :-)

I was just aroused by the fact, that no desktop-sound system under
Ubuntu works with jackd, though this is feasible as pulse and xinelib
both support jackd if only this is compiled into them...

BTW: Ardour has jackd-support even though it is officially a part of UBS
(and thus a part of a UBUNTU-Flavour as "official" as KUBUNTU or
XUBUNTU...) so would it be possible, to have xinelib/pulse plus
jackd-plugins as a part of UBS?

A bit tangent to the disscussion...
Latency issues aside, I've been experimenting, to no avail, to be able to
receive audio from my firewire device and output it to my onboard audio.

I have not been able to get pulse or alsa to show up as an output in Jack.

In this case latency is not an issue, I just want to avoid having to switch
physical cabling back and forth.

Not /really/ accurate. I never said anything about the core-devs. :)
JACK was in Main at one point but was demoted. (I'll try to get the
exact reason later) But there are lots of people (besides audio users)
that would like to see JACK back in Main. It's just gonna take some work
but is on our radar for this (Jaunty) release.

It should also be noted that using the Pulse-JACK plugin just adds
latency and that hard-core users will just use JACK. The plugin will
help new/casual users and people who want PA/JACK apps to talk to each
other.

The pieces are already present, were they packaged for easier
installation/included in the distro, that would make the
"all-inclusive multimedia package" a more valid claim, as color
management is ESSENTIAL to billable hours for graphic arts or
photography concerns.
As one of the audio users mentioned earlier, some of us would rather
spend the time with billable hours projects than tweaking and
debugging software.

Everything, I repeat: everything Video/Graphics people can possibly want
from a Linux Distro, is in the standard (K)(X)UBUNTU. It would be
marketing at best to provide a whatsoever "special" distro for people,
that only want to cut some movies and design graphics.
The one and only relevant reason for a special distro like UBS, CCRMA or
 JAD is in fact the RT-capability including am optimized Kernel and a
proper automagic to configure the system to work with it (limits.conf,
timer resolution and firewire-setup).
If the latter is not a must-have, UBS would be nothing but a theme(many
people dislike) and a set of preinstalled apps (everybody can install
with a few clicks in synaptic).

> Graphics and Video people benefit greatly from
> Pulse.

If this is so (I doubt it is...) may it be: there are a lot of UBS-users
like me, that prefer XFCE or KDE, Fluxbox etc. instead of GNOME and we
all still accept, that GNOME is the standard-desktop for UBS. We simply
install whatever DE we like and use the apps and have the benefit of the
RT-optimisation as well.
But pulse interferes with audio and so it should be removed from UBS, it
would be OK with me, if it is installed but I would like to have a
simple way to get rid of it. Ubuntu Studio Control should have a switch
for that: disable pulseaudio, click, done

The situation could be different if only the available jackd-plugin for
pulse would be installable, the same situation for xinelib.

There is NO sane reason not to have these plugins in universe and there
is absolutely not the slightest reason not to install these plugins with
UBS.
Cory has pointed out later on in this thread, that the core-devs do not
want  the jackd-plugin in pulse, because jackd is not in main - they
don't want to cope with that, because they do not care for audio-users,
I'd say. The UBS-team should not accept such politics lightly...

Anyway I have a Suse11.1 up and running now and thanks to jengelh with
the best RT-support I have seen since 64Studio 2.0. I run jackd all the
time with 8ms latency, no xruns on a machine on which the recent UBS
does not run jackd with less then 40ms.
And yes: of course you can install pulse and xinelib with proper
jackd-support with a few mouseclicks in Suse.
So I will see, how 9.04 improves the situation...

Khashayar,

I can't actually answer this completely, as we don't have an RT environment
with which to make a comparison. But i will say, from my own humble
experience, that Linux runs faster on my little laptop, than mac ever did.

I'll make a correction here too. I'm using KUBUNTU HARDY, as i don't know if
that makes any difference for a "Ubuntu vs ?" comparison.
I also have enough foolhardy bravura/courage/pick one... in me to install
and try up to date packages from source/svn/etc... and so far i've either
been clever, or extremely lucky. I built a tiny linuxsampler template of
modest gig files as a sound engine, that runs ok for playback/recording (the
G4 is 867mhz, 512mb ram, titanium version), and rosegarden ticks along
without complaint, or stalling.

One thing is for sure from my personal experience. The G4 has a new lease of
life, and when i'm traveling, it serves well as a modest musical notepad for
that moment of sudden inspiration. :)

It would be fair to say that with any sizable arrangement, this size laptop
might struggle, but that would be true (and indeed was) running mac as well.
I've got further with the linux distro install, if that gives you some
indication of the worth of such a change.

Alex.

Cory, I've only got an older G4 laptop, but you can count me in for testing.
(Sadly, i can't code)

Alex.

32bit Ubuntustudio Hardy 8.0.4 (2.6.24-23 RT)
64bit Ubuntustudio Hardy 8.0.4 (2.6.24-23 RT)
PPC Kubuntu Hardy 8.0.4 (2.6.24-23 generic)

All major audio stuff, including Alsa and Jack2, installed from up to date
source.

As far as latency with Pulse *generally* goes, I've spoken with Lennart
himself and it cannot (and maybe will not) go where JACK does. If JACK
were in the main repo we could get the Pulse/JACK plugin compiled but
that adds latency as well.

I'm actually a little confused by the confusion. Starting JACK with
JACKcontrol, Pulse should be stopped for as long as JACKcontrol is
going. I forget but it *might* even be tied to jackd itself. Luke can
chime in here.

If we got someone to get together the -RT kernel and testing we would
for sure put out a PPC Studio. We've just lacked the man-power.

This sounds interesting.
I have an old iBook G4 with 768M of ram, running as a sort of server
currently. Would you recommend that machine as a Linux DAW instead? I
always thought it would be too slow for that sort of thing.

Re: Pulse ?

Eric,



I can run with Video people possibly benefiting from using Pulse (any more
or less than alsa/jack? I write music to image, and jack does fine here),
but i'm a bit lost as to how Graphics people might prefer pulse over jack or
alsa or oss or anything else.

I don't understand your answer to the pulse latency question. You were quick
enough to tell me i'm wrong, but then cited ESD as 'worse' than pulse,
without any sort of clue as to actual latency in pulse or not. Seems like a
bit of a red herring.

You're completely off the mark with Ubuntu ppc. It's already done, and
works, maintained as a community project. Package selection is large (as
large as any other ubuntu from what i can see), and one can install from
source without a hassle. I have RG 1.7.3svn running on my G4 a.k.a. UBUNTU
HARDY PPC, as well as ardour 2, AND ardour 3. All installed from source
without any extra pain or hassle. (Only missing the RT kernel)

A quick google would reveal all this to you, of course..

First and foremost, I'd like to remind everyone not to 'top post' as it
throws off the natural reading of a conversation.

Next, I think it's good to point out in this argument, that UBStudio is NOT
an audio specific distribution - it's a multimedia specific distribution.
Audio users may make up a large portion of the user base,  but they're not
the only cats in town.  Graphics and Video people benefit greatly from
Pulse.

Also, you're wrong (from what I know on the subject) about the Pulse latency
issue.  ESD - the software that pulse replaces - has a much higher latency
time than Pulse.  Not to mention, much less features, and no jack
compatibility or links (very useful for ffado people who want to play system
audio over jack).

Lastly, the powerpc is really not feasible in a sub-distro of Ubuntu -
unless Ubuntu (main) starts supporting powerpc.  It's not just the kernel
that would need to be built; every single binary package would need
recompiling for that architecture.  Debian, however, does do powerpc.  I'd
recomend you look into rolling your own RT kernel for debian if you need
powerpc support, as it's very similar to Ubuntu.

Hi Beldon

I'm proberly not the most qualified to tell you this :-) This might not 
work on your system, it's just what I have found to work on my own Hardy.

***

% sudo apt-get install alsa-oss
% sudo apt-get install libasound2
% sudo apt-get install libasound2-plugins
% sudo apt-get install sysv-rc-conf
% sudo mv /etc/X11/Xsession.d/70pulseaudio ~/
% gconftool-2 -s -t bool 
/apps/gnome_settings_daemon/plugins/sound/active false
% asoundconf unset-pulseaudio

% sudo sysv-rc-conf
Page down till you see “pulseaudio” entry, then untick all the box []. 
Save and exit.

% asoundconf list
Names of available sound cards, mine is M2496 so I use this line :
% asoundconf set-default-card M2496

Make sure libao.conf is set to ALSA
% sudo gedit /etc/libao.conf
defaul_driver=alsa

Navigate from the menu: System - Preferences - Sound, make sure your 
only use ALSA
Under Sounds - disable system sounds

***

This might be total overkill, but it works for me :-)
Someone resently told me that these simple three lines is enough :

% sudo apt-get purge pulseaudio
% asoundconf list (Names of available sound cards: M2496)
% asoundconf set-default-card M2496

And just to clarify... I don't hate Pulse, I just don't use it :-)

btw. If someone can tell me a correct way to do this, I'd be happy to 
make a script and host it on my site.

Re: Pulse ?

[alex stone]

Why can't we make pulse optional in UBStudio?

I understand UBS as an audio specific distro that focuses on
audio/multimedia production. We use RT, Jack, etc, knowing precisely what
UBS is designed for.

The only version of pulse i have installed now is in the laptop that i use
for admin (Ubuntu Hardy). In that environment it serves me well, and
objectively, i don't think it will be long before pulse becomes the generic
audio choice for most distros, as it provides a common framework for devs to
work with, something we could do with more of on the linux planet.

However UBStudio, and other audio specific distros, are designed for a
purpose, that, in most cases, requires a RT, or near realtime specific
environment in which we gain the most advantage. As i understand it, pulse
already introduces a degree of latency in it's operation that is
counterproductive to realtime audio work. (Correct me if i have the bear by
the wrong ear here.)

In reference to my note about the laptop, i'd find it more useful if the UBS
team could devote a little time in consideration of building an RT kernel
for powerpc owners, be it laptops like mine (G4, circa 1800) to the powerful
beasts that came out before apple went intel.

I'm confident there's more than one user who has a spare ppc computer
gathering dust that's crying out for use as a second box, driving
linuxsampler, or plugins, etc...

My little laptop with UB hardy ppc runs a good deal faster than it ever did
with mac, and i'd dearly like to see it do the gazelle thing, speaking
audiosyncratically, of course.

So UBS pulse out, and ppc UB RT in here.



Alex.

Well I certainly regularly use and enjoy the features, and ease-of-use, that
Pulse brings to my laptop.  Furthermore, as it's the desired central hub for
Ubuntu's (current and) future sound chain, it's unlikely that a disable
option will be looked upon as a beneficial feature by the devs.  Such an
option would just allow application developers to forget about adding proper
Pulse support.  It would also probably cause many more issues than it solves
from uneducated people opting out of Pulse or having their system messed up
by the script at some point (there'd also need to be a feature to re-install
Pulse as default should one change their mind).  Currently, the removal of
Pulse is a 'remove at your own discretion' modification; changing that to an
install-time operation would imply official support for non-Pulse systems
(this is the biggest issue behind your idea) and would require a large
number of devs to bug-check and maintain this branch of the sound-server
setup.

Essentially, the sound-server setup is complicated enough as it is; adding
official non-Pulse support would just add to everyone's headaches (and yes
this includes the end-user).

The closest thing I could imagine to what you're asking for, is: if you (or
some other Pulse-hater) wrote a program/script that uninstalled Pulse,
released it, refined it, fixed it, added a GUI, and packaged it for
inclusion into Ubuntu's Universe repository, then it might get accepted.
But I doubt that even then would it be included as an installable option on
startup.


Just my point of view.

Re: Pulse ?

[wayne]

ahoy all,

this may reveal my cluelessness, but why is Pulse such a problem for
recording audio/MIDI?  with the latest 8.04 real-time kernel, i have
noticed no problems with Pulse per se (more problems with Macbook
built-in audio ALSA driver/position_fix issues).

thanks for the edu in adv.

Pulse ?

[sandie]

Hi all

One of the first things I do when installing a new UbuntuStudio, is 
purging the system of Pulse and setting the system to use Alsa. I have 
done it so many times by now, and have even thought of making a script 
that automates the process.
I know I'm not the only one who doesnt use Pulse in UbuntuSudio, in 
fact, I don't think I have ever heard of anyone using their pc 
UbuntuStudio machine for audio/midi-production who uses Pulse :-)
Can't we have an option to NOT use Pulse in the install ?

With kind regards and respect to the UbuntuStudio devs

What version of Virtualbox are you running? I'm on v2.0.4 (Hardy,
latest patch from two days ago) on top of Intrepid 8.10RC AMD64 with
the generic 2.6.27-7 kernel. That vBox runs fine even though it's not
officially yet on Intrepid. The audio works properly on the 8.10RC
with both pulseaudio (finally, after numerous false starts, yeah) and
OSS inside the vBox, and using pulseaudio, OSS and ALSA directly under
Intrepid.

For the longest time under vBox (on Hardy and the Intrepid Alpha &
Beta) I had to configure my sound setup for OSS. Regardless of what I
ran native. Now it seems to all be working (perfectly, fingers
crossed) as pulseaudio across the board. This is on my desktop and DAW
boxes that I've moved forward to Intrepid. All of which are recent AMD
motherboards using recent Nvidia chipsets. I have no idea how well any
of this might work on a laptop since mine is an 8 year old PIII that
dual boots Win2K and Darya Mint.

As for Samba, all I can tell you is that I used to have to reset my
shares every time I rebooted. Those are at least now holding in the
Intrepid 8.10RC and my sons (on WinXP) don't bitch at me because they
can't reach the sample libraries housed in a share on one of the
machines. My suggestion would be that if you have more than one
machine available, try taking one of them forward to the 8.10RC using
the generic kernel (since the rt is not there yet). And see what
happens. It will at least allow you to check out if things like Samba
and pulseaudio will work properly for you. YMMV.

runs Ubuntu Hardy. No problems there with system sounds at all. So its
definitely the configuration used with UStudio.

Well, I tried it on my test system (upgraded from alpha4) with an pci
card for PA and an usb device for jack, and PA doesn't shut down. Maybe
it's an update-related-problem. It is no problem to me however.

I'll do a fresh install once hardy is released. We'll see if it's still
the same then.

Philipp

Well, looking at the wrapper script at /usr/bin/qjackctl, if
pulseaudio is running and pasuspender is installed,
/usr/bin/qjackctl.bin is called via the latter, which will disable
Pulse for the duration of the process, regardless of what Pulse is
doing, which card it is accessing, etc. A very hacky solution, but
functional(ish).

I haven't tried it yet, I think it doesn't shut down if jack and pulse
audio are running on different interfaces. Maybe I should have said
interface instead of device previously.

If you use qjackctl (JACK Control), it does, no?

What does not work is pulseaudio and portaudio apps. So if you try to
use for example audacity with pulseaudios alsa-emulation you are out of
luck. In that case you would need to shut pulseaudio down and use alsa
natively.
Another thing is that the output level of stuff that goes through
pulseaudio is a lot lower than with just alsa.

Pulseaudio should shut down the moment you start jack (if they use the
same device) and thus it shouldn't affect you if you use jack.

I think - nothing. It just expand networked audio possibilities. LTSP5 
use it on the Ubuntu's thin client system.

Thin client on the Hardy Beta x86_64:

Here is same machine (LTSP5 Server) working as Studio:

I do not see Pulse Audio anywhere, I just use Jackd, that's the base.

How will Pulse Audio change things for me?

[[EMAIL PROTECTED]]

I've been reading a bit up on Pulse Audio, slated to be included as the
default sound server in 8.04:

http://en.wikipedia.org/wiki/Pulse_audio

My question is, how will Pulse Audio, in actual practice, change things for
me as a Linux-based musician?
