I upgraded from chimaera to daedalus Friday night.
Today for the first time I joined a meeting on zoom, using the zoom app
invoked from firefox-esr.
The audio is very very quiet. Hard to understand the spoken voice.
Befre the upgrade I had no such problem.

Does daedalus have some new audio subsystem I need to adjust?
The usual pulseaudio volume control doesn't seem to help.
