I have also observed a similar behavior
with Ubuntu 20.04

UTC 2021 x86_64 x86_64 x86_64 GNU/Linux
and Firefox 88.0.1 (AMD64 Platform).
For me this bug also causes other applications to be distorted, too.

Note that the behavior occurred when the Logitex C615 has been unplugged.
I was just curious, because Dave Evans has the same webcam so I could not
exclude that
this may be related.

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.
