Okay, I found a solution/work-around, although the fact that it
stopped working seems to be caused by a regression via updates. Though
I suppose the people experiencing it could have something else
problematic in common. What I needed to do to get the internal mic
working was run "sudo alsamixer", navigate over to "Digital Input
Source" via the arrow keys, and press "+" to change it from "Analog
Inputs" to "Digital Mic 1". Then everything was working again like it
was a week or so ago! I believe then you need to run "sudo alsactl
store" to make it stick. Attached is a screenshot of the alsamixer
setting.

Any ideas on if anything in the sound stack changed recently that
would change the "Digital" Input Source to use "Analog" Inputs? That
setting doesn't even seem to make sense.
