At some point in the last month (I think), firefox stopped getting
microphone audio from my USB webcam. I've tried another webcam, and a
USB audio adapter. When I go to a website that needs audio, such as a
videoconference, I get prompted to allow the microphone, which I allow,
but no audio goes through. When using mictests.com, it recognizes that I
have a microphone named "default", which makes sense for sndio, but no
audio is detected.
Microphone audio works fine in ungoogled chromium, and other
applications.
I'm not sure when this started, since I only rarely use the microphone
in firefox, but it would be nice to not need chromium for my video
calls. I *think* it was working on 19 April when I had a video call.
It's also possible I joined that call from Linux.
Any thoughts of where to continue debugging?
