Thanks for the reply, Poly.

Tested with this:

Mixer vol      is currently set to  84:84
Mixer pcm      is currently set to  96:96
Mixer speaker  is currently set to  85:85
Mixer line     is currently set to  20:20
Mixer mic      is currently set to 100:100
Mixer mix      is currently set to  94:94 *
Mixer rec      is currently set to 100:100 *
Mixer igain    is currently set to 100:100
Mixer ogain    is currently set to 100:100
Recording source: mic

On these sites:

https://webcammictest.com/check-mic.html
https://www.onlinemictest.com/

Firefox finds the mic but no input back in
Chromium doesn't even find the mic.

The webcam works on both.

Audacity doesn't record anything from the mic.

Thanks for trying.
