I recently updated my Ubuntu 19 to 20.04 and started experiencing strange issue: when I open sound settings and switch "output device" while my headphones are plugged in - sound goes out of headphones no matter what device I have chosen. The only thing, which seem to help, is plugging off my headphones.
This was not the case with Ubuntu 19. I could easily switch between built-in speakers on my laptop and headphones in the settings and it worked fine.
Has anyone else encountered such issue? Is there a way to fix it?
I believe my Ubuntu was 19.10 (but I am not sure about the minor version). My kernel seem unchanged after upgrade - 5.4.0-29-generic. The hardware, obviously, haven't changed either.
