Simple question - have you installed rt-kernel?

[EMAIL PROTECTED]:~$ uname -a
Linux ubuntu 2.6.22-14-rt #1 SMP PREEMPT RT Mon Oct 15 01:05:51 GMT 2007 
i686 GNU/Linux
[EMAIL PROTECTED]:~$

[EMAIL PROTECTED]:~$ apt-cache search linux-rt
linux-image-2.6.22-14-rt - Linux kernel image for version 2.6.22 on RT 
kernel
linux-rt - Complete Linux kernel on realtime kernel
[EMAIL PROTECTED]:~$

If yes, then there is few steps to left.

1. Add snd-seq to /etc/modules

2. Add dev.rtc.max-user-freq=1024  to /etc/sysctl.conf

3. Add @audio - nice -10 to /etc/security/limits.conf

4. Add new mount point - sudo mkdir /mnt/ramfs

5. Add new lines to /etc/fstab:

none/tmp/jack   tmpfs   defaults0   0
none/mnt/ramfs  tmpfs   defaults0   0

6. Reboot your machine.

You do not understand finnish language (I think), but you understand 
screenshots:

http://wiki.ubuntu-fi.org/Ubuntu_Studio#head-9b23d1fc929cbe800a10e9a24e7747e16b04ba26

7. You need sound fonts for Qsynth (I have M-Audio keystation 49e for 
Jackd, Qsynth and Rosegarden):

Terratec phase 88 rack PCI

[Franz Zanne]

Someone knows if the terratec phase 88 rack pci is supported by the alsa
driver? I'm unable to find information about this item, but I know that it
uses the Envy 24-HT and ubuntustudio has installed the Envy 24 Control.

I think that it should be supported, but I need to be sure before to expend
so money.

Thanks for informations.

Just a minor correction, Linux has been ready for this task for quite
some time now.  DeMuDi and the successor 64studio have been stable and
capable for many years.  I still use 64studio on the production box,
UbuntuStudio is for the laptop which already has *Ubuntu (my Desktop OS).

What sound card do you have?

What is the error?

What are the contents of /etc/security/limits.conf?

The strace output that is suggested elsewhere in this thread is useful
as well.

Re: How to find out what app is hogging the soundcard

It was probably using the OSS emulation interface of /dev/dsp which you
were not checking before.

So in the future do fuser /dev/dsp as well.

 I use ubuntustudio 7.10 from a fresh install + xfce.
 It worked previously but I don't know what I did to break it.

Re: Ubuntu Studio & Qsampler

[Chris Dawson]

strace is "system call trace."  It simply runs a program within a
harness that outputs all the system calls made.  In this case, it will
output and tell you where the jackd program is dying.  In my case I
saw that it was dying when it tried to open and write to the
directory.

It is absolutely harmless to run strace, it just outputs a lot of
extra information you probably won't understand, but would be useful.
If you'd like run it and send me the output.  You can do this:

strace -ooutput.txt /usr/bin/jackd -R -u -dalsa -dhw:0 -r44100 -p1024 -n2 &

Then, it'll either die on its own, or you'll need to run:

killall -9 strace jackd

...to kill it.  Then, send me the output.txt file and I can look for
something suspicious.  Or, you can check it out youself and perhaps
you can figure it out.

My output shows exactly the same permissions:

Re: Ubuntu Studio & Qsampler

[Chris Dawson]

Oh, you know what, I recall that when I upgraded Ubuntu-Studio did not
properly set the permissions of /dev/shm, the shared memory directory.
 Can you verify the permissions of that?  Mine is

[EMAIL PROTECTED]:~$ ls -l /dev | grep shm
drwxrwxrwt 2 root   root  40 2007-11-12 14:37 shm

Does yours show the same?

You might also run jack under strace, like so:

strace /usr/bin/jackd -R -u -dalsa -dhw:0 -r44100 -p1024 -n2

I think this is where I discovered it could not open the shm directory
and create files there.

RE: gnome settings manager error to start desktop

[Greg K .]

You're not alone!
See this too: 
https://bugs.launchpad.net/gnome-control-center/+bug/140469

I guess we just have to wait for a patch or something...

Re: jackd crashing

Clicking on messages in jack control will give you output.

Essentially you should be using a realtime kernel to use the realtime
option.

You may wish to increase your periods/buffer (under settings in jack
control) to 4.  This is what I use for the integrated sound device on my
Turion based laptop.

Yup, looks like I'm good to go - Wonder why I can't enable realtime?

Re: Ubuntu Studio & Qsampler

[Chris Dawson]

If I recall correctly, by default my upgrade did not include the
realtime kernel.  I had to apt-get that myself, and then when I
rebooted I could run jack with realtime.  See if that works for you.
You can see if you have the realtime kernel by doing this:

[EMAIL PROTECTED]:~$ uname -r
2.6.22-14-rt

If you don't see rt, then you are not running realtime.

Ubuntu Studio & Qsampler

[[EMAIL PROTECTED]]

So I bit the bullet this weekend and chose Ubuntu Studio for my Gutsy
upgrade and... Wow! Seriously well done..! I can finally feel confident
using Linux as my primary music production OS..!

One question, one gripe, and one solution:

Question: How do I enable realtime in jack? From my understanding, Ubuntu
Studio includes the realtime kernel, but whenever I check the realtime box
in Jack, it won't start - Any ideas?

Gripe: I love the theme with a few exceptions, the largest of which is
being able to see the fine lines between devices and apps in qjackctl's
connections panel. Any suggestions for a fix?

Solution: I couldn't for the life of me get Qsampler to work - Kept saying
every time I started it that "Server could not be started". A bit of
research turned up that linuxsampler, the sampler that Qsampler is a GUI
front end for, is not included w/ Ubuntu* due to licensing issues. Some more
digging around turned up these Ubuntu debs for linuxsampler:
http://ubuntu2.cica.es/ubuntu/ubuntu/pool/universe/l/linuxsampler/

One quick double click and qsampler is now working flawlessly! Perhaps there
should be a note about this somewhere? It took me aages to figure out.

Thanks again for putting together a great distro!

Hello Cory,

I have uese k3b with kde for a long time. When I converted t
UbuntuStudio I download k3b to go with my Gnome app and it has worked
fine. I guess I prefer it to other apps because I have used it and
find it works very well for me.

gnome settings manager error to start desktop

[Jarbas Jacome]

Hello,

does any body have the same bug with UbuntuStudio?

Sometimes, when I start UbuntuStudio, I receive this error message:

"Did not receive a reply. Possible causes include: the remote
application did not send a reply, the message bus security policy
blocked the reply, the reply timeout expired, or the network
connection was broken.

GNOME will try to load settings manager in the next time it starts."

when its happens, a lot of stuffs don work well, including theme
configs, hd drives arent mounted, etc.

I've found a link about it:

Re: More "feature-rich" burning app for Ubuntu Studio-Hardy.

[Cory K.]

So it's looking like K3b will be included in Ubuntu Studio 8.04 (Hardy).
(this is about 75% for sure)

Testing will be done throughout the cycle to make sure there are no
hiccups. Users will need to give the development team feedback on this
one. ;)

If K3B is found to not integrate into GNOME as well as other apps (ie:
Gnomebaker) and doesn't really provide anything significant over other
apps than this decision will be changed.

Id like to hear what significant advantages there are to K3B over other
apps. We're looking for the best app for what we do in Ubuntu Studio so
the examples need to be related to multimedia production somehow.
