I occasionally participate in Zoom calls using my Android tablet, and
everything Just Works(tm). I'd like to do the same on my desktop with
Fedora, but despite testing three different cheap webcams the big issue
is always with the sound. I can hear the other people perfectly, and
the video is fine, but the audio from my side is muddy and nearly
impossible to understand. I've tried with and without headphones in
case it's a feedback issue (though not using the headphone mic). It
doesn't make any difference. Surely not all the webcam mics can be so
bad? How would anyone ever use them?

Is there some Pulse filter I can use to improve the audio quality? What
are people doing in this situation?
