Mic doesn't work means recording fails. Except if, during the recording,
I use the "Input Source" control to change to another input, *and then
back* to "Internal Mic".
If I start another recording, it will still be silent unless I repeat the
previous sequence.

I don't use mic directly for playback (with hardware a-a path)

Please find the full log and alsa-info in attachment with power_save=1.
