Sorry... Was quite busy recently, and I'm trying to get all our patches
upstream now...

Yeah I have some glitches too... For "Input source" I have "Front Mic",
"Mic" and "Line", while only "Mic" and "Line" are useful. I also have a
Mic as Output which is not relevant (no Mic jack)... I'll try to have a
look at this.

Also, to get the Mic to work, even if the "Input Source" is set to Mic
at boot time, I have to switch to Line or Front Mic and then back to Mic.

I saw your patch. Thx.
