Running Ubuntu 20.04 and I have the same issue with Firefox.
Watching Netflix works fine, till I go to some sites that has a tendency to crash audio. Then all audio goes garbled. Even doing an audio test in settings gives a garbled echo result.
When audio is crashed like this the pulseaudio service uses high CPU even when no audio is being played.
Opening a terminal and running "pulseaudio -k" to restart pulseaudio seems to fix the issue without closing Firefox or all the media apps.
