Additionally, GNOME sound controls look grayed out (https://multimedialib.files.wordpress.com/2020/01/sound-controls-disabled-2020-01-09.png) and turning up the volume there does nothing.

Dimakakos, that didn't work. However, I found that every time a reboot, the sound problem is fixed, and GNOME sound controls work alright again; but if I log out and back in, sound is silenced and GNOME sound controls are disabled again.

I don't know where to look for information about possible errors...
