My webcam’s microphone isn’t recognized by settings (not available under sounds - input) or applications (e.g., Teams, which is where I need it).
It is recognized by alsa, and I can change its gain via alsamixer.
Where do I go from here for troubleshooting? (I don’t know much about audio in linux, but I’m comfortable with a command-line.)
Hmm. It seems to be working now, but I’m confused.
I previously tried both audio input sources (OrbiCam analog and spdif), and neither produced any audio signal. And I got an error from Teams about audio not working. Teams correctly identifies my camera as “HD Pro Webcam C920” but my audio is described as “OrbiCam Analog Stereo” (similar to what’s in settings).
Alsa recognized my audio as HD Pro Webcam C920 (no mention of OrbiCam).
Anyway, it worked fine in arecord, and in Sound Recorder, and now in Teams.
Not sure why it didn’t work before, but it works now.
The names displayed in audio settings are confusing because they don't match the hardware names.
