Recently all my audio disappeared in Ubuntu Studio 21.10 with KDE desktop.

It all worked fine until today, and now there is no audio. I installed 
Kmix and the sound came back, but in the KDE System Settings program it 
no longer lists any section for Audio, which was there before.

The volume icon had disappeared from the main Panel, but one reappeared 
after installing Kmix, at which point audio was working again, but just 
for a short time, as the audio stopped working again after rebooting.

I had tried uninstalling and reinstalling pulseaudio but no change.

I have tried restarting pulseaudio, or using pulseaudio -k to kill it 
which had worked yesterday when the audio did not come on at bootup, but 
it had worked okay after that. Today even that does not work.

What can I do to get back the audio? And to have it listed in the System 
Settings? And to get back the original icon for sound in the Panel that 
I had before?
