Analog audio output vanished today

Hi.

Today the usual analog line-out option disappeared from the audio volume settings ; i have no sound going to my amplifier and speakers.
I also have a digital audio output, but even when selected, no sound is played.
Finally, i have inbuilt speakers in my monitor, that can be persuaded to work if selected (works, but those speakers are really limited, quality is poor).

I have tried rebooting under all the kernels from 5.8 to 5.10, it doesn’t solve it.
Can someone help me?

Any insights/suggestions/comments will be greatly appreciated

Pauvcontrol as a front- end has helped me a lot over the years in understanding my sound sources, which may help to show where the problem lies.
