Public bug reported: After suspending the computer the default sound device is gone and the sound output now defaults to the HDMI out.
Resetting pulseaudio with pulseaudio -k makes no difference, removing the user pulseaudio config and killing / restarting the server as explained in some troubleshoot guides doesn't make any difference either. The only solution seems to be to restart the computer. This is happening in two different computers recently updated to 20.04 from 19.10 one of them and from 18.04 the other. Alsamixer seems to show the default sound device but pulseaudio can't see it ** Affects: linphone (Ubuntu) Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1876316 Title: Default line out device missing after suspend in 20.04 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linphone/+bug/1876316/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
