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.
