Cannot play videos if audio is recorded with Pulseaudio

[Nathan Teodosio]

I use simplescreenrecorder to record screen.

If I use ALSA, I can play the recorded videos with MPV, i.e. all is fine.

If I use Pulseaudio, the resulting videos are not playable. Attached is the output of mpv -v -v for each of them.

PS: I cannot screen cast with the Gnome Shell built-in tool either. The video recorder button does not even show up.

Solved with "apt install gnome-desktop^", which, apropos, removed
Pulseaudio from my system.
