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)
My solution was to add a bridge to pulseaudio, to get all audio passed over to jack.
You might have to install the following package first, like
$ sudo apt install pulseaudio-module-jack
Then you can add the module with:
$ pactl load-module module-jack-sink
If you enable jack dbus interface in the jack settings you can also add
$ pactl load-module module-jackdbus-detect
This will enable pulseaudio to automatically load the jack-sink and jack-source modules as soon as jack is started.
The last step is to set the sound device in your system settings to JACK sink (PulseAudio Jack Sink) and JACK source for input.

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.
