Re: [ubuntu-studio-users] weird behaviour firewire

[bart deruyter]

I already had jackdbus disabled in my search for a solution, was one of the
steps I took. And I filed a bug report, describing behavior with
pulseaudio-module-jack, and without it, in case I'm not alone with this
issue. In Ubuntu 14.10 this wasn't an issue either for me and I kept it in
place too. Luckily, using two sound cards, internal for regular audio, and
audiofire12 for real audio work goes just fine :-).

 @ Mike Holstein:

 my mistake I set the examples in the wrong order, usually I do first
 exit jack, don't hammer on it.* It is not the biggest issue.* Any way
 it happens, exiting jack and trying to start it again, even when I keep the
 device on, I don't get jack working anymore.

 And it's not my first day using ubuntustudio, I'm not a beginner, using
 it sort of hapily for 7 years now, so I do have some experience. Until now
 I never had any problem with exiting jack to start it again later on.
 Secondly I do use the internet to communicate too, not just to browse
 around a little, talking to other people who make music, browsing for
 samples, etc...

 I do not intend to invest in a second machine and I do expect my
 computer to handle audio work and some simple tasks as typing a letter of
 browsing the internet. I simply don't have the funds for it and I don't
 want to scale the philosophy of "for each task a different program" up to
 "for each task a different computer".

 Hi all,

 as an idea to get jackdbus stopping and then startup again I used as
 Edward Schrober suggested :

 sudo kill -9 4327 (the number is the pid of jackdbus)

 but to no avail, jack won't start again. Now I'm on xfce, default for
 ubuntustudio. So it is not gnome related, but a more general configuration
 issue I think.

Re: [ubuntu-studio-users] weird behaviour firewire

[bart deruyter]

Hi all,

I think I have found the solution. I still have to test it more in depth,
but so far it seems to have worked. The culprit probably was
pulseaudio-module-jack.
I uninstalled it and now it seems to work just fine.

So, if anyone else might have this problem of jackd not wanting to start
again after having exited in the same session, and doesn't need it the
pulse-jack sink: remove pulseaudio-module-jack.

grtz,

Bart

 Hi all,

 I'm running ubuntu 15.04 now, gnome variant, with ubuntustudio and
 kxstudio installed through software sources.

 My soundcard is an Echo Audiofire 12, connected with firewire.

 Since 15.04 when I start jack it works fine as long as I don't run any
 other application which requires sound, before starting jack.

 it is consistently going wrong when I for example start chrome, exit
 chrome and try to start jack, using claudia, or qjackctl, or commandline.
 the message qjackctl throws is: JackServer::Open failed with -1

 When I log out of the system, then log in again (no reboot required) it
 works again, as long as I start jack first.

 Also, when I use chrome while running jack things seem to keep working,
 though I have ben thrown out of jack too.

 - I checked if I was in audio-group, which I am, otherwise it wouldn't
 work at all.
 - I turned autospawn off for pulseaudio and killed pulseaudio befor
 starting jack
 - tried out various settings in qjackctl.

 None seem to have helped.

 How can I trace the source of the problem? If it is a known issue,
 anyone idea's on how to fix this?

 Bart

Re: [ubuntu-studio-users] weird behaviour firewire

[bart deruyter]

Hi all,

as an idea to get jackdbus stopping and then startup again I used as
Edward Schrober suggested :

sudo kill -9 4327 (the number is the pid of jackdbus)

but to no avail, jack won't start again. Now I'm on xfce, default for
ubuntustudio. So it is not gnome related, but a more general configuration
issue I think.

grtz,

Bart

[ubuntu-studio-users] weird behaviour firewire

[bart deruyter]

Hi all,

I'm running ubuntu 15.04 now, gnome variant, with ubuntustudio and kxstudio
installed through software sources.

My soundcard is an Echo Audiofire 12, connected with firewire.

Since 15.04 when I start jack it works fine as long as I don't run any
other application which requires sound, before starting jack.

it is consistently going wrong when I for example start chrome, exit chrome
and try to start jack, using claudia, or qjackctl, or commandline.
the message qjackctl throws is: JackServer::Open failed with -1

When I log out of the system, then log in again (no reboot required) it
works again, as long as I start jack first.

Also, when I use chrome while running jack things seem to keep working,
though I have ben thrown out of jack too.

- I checked if I was in audio-group, which I am, otherwise it wouldn't work
at all.
- I turned autospawn off for pulseaudio and killed pulseaudio befor
starting jack
- tried out various settings in qjackctl.

None seem to have helped.

How can I trace the source of the problem? If it is a known issue, anyone
idea's on how to fix this?

grtz,

Bart
