Ach !

Things are actually a bit more complicated. After suspend/resume my
mic stopped working.
After a lengthy testing the minimum sequence that seems to reliably work is:

1/ modprobe snd-hda-intel model=,dell-headset-multi
But **with a headset plugged in in the combo jack**. Else it does not work.

2/ using alsamixer set the second capture knob (that was at 0) to 100

3/ rmmod snd-hda-intel. The headset can be removed now, or not.

4/ modprobe snd-hda-intel model=,headset-mic

5/ Now the proper boost and recording levels can be set in alsamixer,
and the mic works properly.
