I had done it before but tried again and it didn't make any difference.

Definitely something is odd. Today boot was clean of alsactl errors but after reboot/poweroff they appear again.

Led seemed to be always ON first but then went OFF on subsequent boots.

Yes.
But mic status led is not only bug.
It seems to work great using headset, but if you enable mic headset and status led turns off you had enable internal mic too...

Downgraded packages. Microsophone is too low, but led status work.
I need to test audio in virtualbox if it's work.

Just an update, everything is now working as it was before. Microphone is now detected and the mute-LED is also working. This thread can be marked as solved.

Seems I spoke too soon, the internal microphone is detected and working. However the mute-LED indicates the mute status of the headset rather than that of the internal microphone

Form me, led is fixed... Update not resolve!
Did you use gnome? What you change?

Only seen your post now, I had changed the file /usr/share/alsa/ucm2/HDA-Intel/HDA-Intel.conf to reflect this change https://github.com/alsa-project/alsa-uc … eaa224b766. Just changed the line Syntax 3 to Syntax 4. The other change I made was just updating my system the normal way. This solved the problem with the internal microphone not being detected but I have an issue with LED where the led indicates mute status of the headset rather than the internal microphone

I have the same issue, but on Fedora 34. A bit annoyed since it is a regression (the led was working fine until some updates ago) but I haven't found any solution yet.
