SUMMARY
After a recent update, the sound completely stops working. With the help of a user here: https://unix.stackexchange.com/questions/742445/audio-stopped-working-after-a-system-update/742530#742530, 
we narrowed it down to a problem with the ALSA drivers on the Linux kernel.

The problematic kernel number is 5.19.0-38, and downgrading to 5.15.0-69 fixes the problem. 

Here's the output of aplay -l:

I think I have a similar issue with kernel 6.2.0-26-generic.

In the process of trying to fix it, I seem to have lost all of the audio devices in the control application, but they still show up in aplay -l

Is there a work around for this?
