When I go to the sound settings, the only output device listed by Ubuntu is "Dummy output". I can't hear any sound. My bluetooth headphones still work if I connect those. These symptoms appeared recently, around the same time as this.
I ran aplay -l
and it says no soundcards found
.
Also worth noting that I dualboot Windows (although I never use Windows) and Windows can play sound through my speakers just fine.
Ubuntu 19.10 on a laptop.
