in gnome settings audio section does not see any sound card

[Mike]

in gnome settings audio section does not see any sound card. if i run alsamixer it can detect the sound card and all works fine. in gnome sound settings everything seems to be disabled.

I have excatly same problem on PC where configuration is completely different than my laptops one.

All the problems started recently, after upgrading to 19.04 some time later one of the updates destroyed all sound

More info after i run pulseaudio --check i can see an output device but its not my sound card, another screenshot attached

[Mike (mike-kulasinski)]

Ok I managed to fix it

rm -rf ~/.config/chrome-remote-desktop/pulse*

Looks like chrome remote desktop app (which i was using) took over my sound card in gnome settings, weird :/

It's good if you can't reproduce a bug any more. Although your AlsaInfo.txt shows the main problem was that pulseaudio wasn't running at all:

Pulseaudio:
      Installed - Yes (/usr/bin/pulseaudio)
      Running - No

Let us know if you wish to investigate that problem again.

[Mike (mike-kulasinski)]

Thanks Daniel, I have reported another bug with the same issue this time with alsa running.

https://bugs.launchpad.net/ubuntu/+source/grub-installer/+bug/1815526

solution is exactly the same

[Mike (mike-kulasinski)]

I just realised that removing chrome remote desktop config isn't enough. Like I mentioned on my PC i had the same issue. I had to remove .config/pulse too and restart to make it work

[Mike (mike-kulasinski)]

Unfortunately it is a recurring bug, and yet again I have no sound detected in gnome settings

@Daniel van Vugt

[Mike (mike-kulasinski)]

also before restart i need to run

pulseaudio -k
pulseaudio -D

and then restart computer

[Daniel van Vugt (vanvugt)]

Next time the problem happens, please check if you have a 'pulseaudio' process running. If not then please follow these instructions:

  https://wiki.ubuntu.com/Bugs/Responses#Missing_a_crash_report_or_having_a_.crash_attachment

If you do however have a 'pulseaudio' process running (as yourself) and still no audio then please run:

  apport-cli --hanging -P PID

where PID is the process ID of the pulseaudio process. Then tell us the new bug ID created.
