[SOLVED] System hangs after shutdown of jack

Postby flappix » Mon Oct 15, 2018 12:12 pm

Hi @ all,
since the last system update (ArchLinuxARM) I have the problem that the system is really slow / sometimes unresponsive after I stop jack. While jack is running everything is fine. When I stop it I get long delays between typing commands an their execution. I type a character and after 10s up to some minutes I see the character in the console.

I installed the previous version of jack which was installed before the update but it did not change anything. Before the system update I didn't have this issue.

It's really annoying because I have to start/stop it very often.

Would be very cool if someone could help :)

Is the problem still when you run

Code: Select all

killall -9 jackdbus qjackctl
(or "jackd" or "Cadence") in the console?
If so then start jack (== qjackctl or Cadence) from the console for testing and start/stop it. What does the console say?

Hi,
thank you very much!
The problem was not jack itself but mod-host, an application using jack. I quit all applications using jack (and jack itself) in a script. Adding -s KILL to all kill commands solved the problem.
