Public bug reported: In Ubuntu 18.04 switching between audio devices worked flawlessly.
After upgrading to 20.04 not so much: When I try to switch between Logitech G930 and Soundblaster X-FI Audio devices, either the system sounds and/or programs which are already started do not playback any sounds. In some cases, system sounds (incl. the sound test) do not play, but programs do. It is really weird and I have a hard time reproducing the issue as well as the solution. Sometimes I play around with alsamixer and switch between the selected sound devices there and afterwards switch the device in the settings panel. It then more often than not works again as intended. If you have any suggestions on how to run down further details for this bug to enable you to bugfix this, tell me and I will try to provide further info.
