    No sound after running ardour and jack

    Hi,

    I installed ardour and jack sound server and sound is working fine in ardour, but I get no sound from any other app. Stopping jack with qjackctl does not help either. Only thing that helps is a reboot. It seems that jack reserves the sound card for itself or something like that, so how can I restore sound without rebooting?

    I'm running 13.04.

    Try 'dpkg-reconfigure -p high jackd'

    Tried this. Did not help. Any other suggestions?

    Had the same problem - jackd is still running.
    In a shell run:

    Code:
    ps -Af | grep jack
    Find the process id of jackd and kill it

    That should do it.

    Hi everybody ! I used to work with Ardour under 12.04. I couldn't listen to other app's sound while I was using Ardour (and therefore Jack).But when I left Ardour, everything was ok, no need to reboot. When I upgraded to 12.10 it began to keep on blocking other app's sound even after Ardour was closed. I moved to 13.04 hoping that this new problem would be solved. But no ! I tried to close Jack but it is still with no sound. What happened ? Why jack follows on now whereas it was not doing it on 12.04 ? Mysteries...

    I have the exact same problem. No process named anything similar to "jack" is running...
