I have the same issue on Xubuntu 20.04. I find that just exiting
Firefox completely and relaunching it resolves the audio problem on
other applications and stays fixed, even after relaunching Firefox,
unless I go to a website that causes the issue to start again. So, it
seems to be very website specific for triggering it. One website that
always triggered it was, strangely enough, www.subway.com. I was in a
live meeting with MS Teams at the same time, but not 100% sure that MS
Teams factored into it except that the audio of the meeting got
scrambled up until I exited Firefox. If I went back to that website
again, it would happen again.
Unlike the other commenters, I don't even have a webcam on this PC at
the moment, so I don't think it's webcam related. But, I do have some
other hardware in common with the previous poster -- specifically Radeon
and Starship/Matisse Audio. At the time of the incident, the audio (of
both MS Teams and Firefox) was playing on the Starship/Matisse Audio
port. But based on all of the comments here, it doesn't seem to be
sound/video card specific, as I'm seeing both Nvidia vs Radeon and Intel
vs AMD throughout this thread.

Title:
Firefox sometimes causes garbled audio
Status in firefox package in Ubuntu:
Confirmed
Status in pulseaudio package in Ubuntu:
Confirmed
Bug description:
Opening certain applications/websites at the same time as Firefox
causes the audio to become garbled.
The audio sounds distorted with an echo.
Certain actions are guaranteed to cause this, but it can also
happening when only running instances of Firefox.
I've been able to consistently cause this by launching Zoom from a link
within Firefox.
This does not occur when using Chrome.
The only way to fix the issue is to shut down all audio-related
programs.
