[bartje <bart.deruyter@xxxxxxxxx>]

I am using the jackd firewire back end and qjackctl, or (mainly) claudia
(from the kxstudio repositories) . The problem was in both instances, jackd
would not start again, and I could not restart a claudia-studio

Using claudia and having a running studio, only jackdbus shows up running
ps x, using qjackctl, in settings I had disabled jackdbus by default, only
jackd shows up.

I've tested another situation, because a minute ago the problem showed up
again, without pulseaudio-module-jack installed. In this case I had turned
on my firewire device after boot. I could start it perfectly, do some work,
stopped claudia and tried to start again, without success.

After a reboot having my firewire device on before booting, the issue
disappeared. I could start jackd and a claudia-studio again after having
stopped it.

Previously I probably had kept my audiofire12 on after rebooting when I had
uninstalled pulseaudio-module-jack, so I figured it must have been that,
but obviously I was wrong.

grtz,

Bart

Title:
  jackd won't start again in the same session after having exited

Status in Ubuntu Studio:
  New

Bug description:
  Actual behavior with pulseaudio-module-jack installed:

  1. start jackd with firewire device.
  2. stop jackd
  3. run application which requires audio, using pulseaudio
  4. exit the application
  5. try to start jackd with firewire device

  result: jackd will fail

  expected behavior: jackd should start

  Without pulseaudio-module-jack the expected result is just fine.

  system: ubuntustudio 15.04 64bit, audio device: audiofire12 (echo)
