Public bug reported:
What you expected to happen
Settings -> Sound -> Input to list internal mic (to test orange bars
for recording from internal mic)
What actually happened
Settings -> Sound -> Input only lists "Digital Input (S/PDIF)" (no bars
move because no digital input connected)
If possible, a minimal series of steps necessary to make it happen,
where step 1 is "start the program"
1. Open Settings
2. Select Sound setting
3. Select Input tab

NOTE: ultimately, I want recording to work in apps such as Chrome,
Firefox, Zoom, etc.
NOTE 2: mic recording was last working in Ubuntu 18.04.x (32-bit)
instance on *same* MacBook hardware (this installation went corrupt so I
can't reverify it still works unfortunately - I will add to this issue
if I get the cycles to reinstall or at your request)
NOTE 3: interestingly enough, while using "ubuntu-bug" it was able to
record from the mic on the 1st (of 2 tests the bug collector initiated).
