I am using 'Centos 7.8.2003 (Core)' and after an update, a week or two 
ago, all system sounds seemed to have stopped working.

Sound in firefox still works, and also rhythmbox seems to play music 
files, VLC player do too.

It seems that  just things like notifications etc are not woring 
anymore. Also, the "test speakers" in the sound setup doesn't seem to 
produce any sound.

any ideas?
