Comment 51 for bug 1840725

Sorry to post so much - I wish I could consolidate or edit all these posts. The next day I came back and it didn't work in Zoom. I tried a bunch of things listed on the following web page, starting with simplest first, from

https://support.system76.com/articles/audio/

until finally I did

sudo apt install --reinstall alsa-base alsa-utils pulseaudio linux-sound-base libasound2

then I rebooted and

sudo alsa force-reload

and it worked. Which is weird, I think, because I just did this reinstall of these modules 3 days ago. I don't think the versions of these modules changed. I don't know what's going on. My guess is that it breaks because something changes a configuration file. And then I guess it's fixed when the configuration file is re-initialized by re-installing these modules. I wish I could pinpoint it.
