No more sound after running Ardour

Question

All the sound works perfect with all the applications on my system. But from the moment I launch Ardour, no more sound comes out from other application than Ardour. The easy way to get it back is to restart the laptop.

This is probably related to Jack ... but it's not clear...

Does anyone know what's going on behind the scene? How to fix it?

in Terminal:$ top | grep jackd, first number in line will be the pid of JACK, kill it with $ kill <pid>. It's the simplest way)

What about `pkill` or `pgrep` instead of `top|grep`? ;) – 0xC0000022L Jul 28 '14 at 11:21
As @0xC0000022L suggested `pkill -9 jackd` also works ;) – 0xC0DEGURU Oct 23 '15 at 16:34

I am still figuring out jack and ardour, but you probably need to stop jack. I use qjackctl which you can find in the software center (if you don't already have it installed). after you finished with ardour hit stop in qjackctl and in my system normal sounds start working again.

Theres probably a more hygienic method, but opening up the task manager and killing the jackd process fixed the same problem for me.

After intalling adour I got no sound from my speakers. In “Sound preferences”, in the “sound output” tab, select “analog audio output”, and I got sound.

Just to share the way I wrote the command to kill jackd:

sudo killall jackd

Hello! This would be better suited as a comment posted upon the answer which suggests to kill the `jackd` process rather than as its own answer. As you have the comment privilege, you should be able to add a comment to the other answer that suggests killing `jackd` by using the "add a comment" button underneath the other comments on that answer. – Thomas Ward Jun 26 '16 at 17:03
