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 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1876316/+subscriptions -- Mailing list: https://launchpad.net/~kernel-packages Post to : kernel-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~kernel-packages More help : https://help.launchpad.net/ListHelp
