Public bug reported:
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.
