All— this fixed the issue for me (M1 Pro):

I'm still on Mojave, but I've found that `sudo killall -9 coreaudiod` when something weird is happening with sound fixes things. For me it is normally that sound doesn't play, though.

Modern syntax:

    sudo launchctl kickstart -kp system/com.apple.audio.coreaudiod

Wow - I do this whith Pulseaudio!

Is this why my 2021 iMac sounds like a jet engine spinning up when I watch a youtube video in Firefox?

I just assumed this was yet another attempt by google to sabotage the competition.

can someone add (2021)?

This problem still exists in 2022.
