Public bug reported:
Mostly I get no sound at all when using the internal mic.
Using sound setting recording level slider I am able to get some (noisy sound).
With alsamixer I can get (also noisy) recordings by lowering "Internal Mic
Boost"
I have applied (and removed)

options snd-hda-intel position_fix=1
