Small update: I cannot really repro anymore that the on-board sound works, 
even if I boot w/o a headset, I saw this correlation several times in the 
past, but right now, pulseaudio always seems to be unhappy with on-board 
sound, e.g. if I boot without USB headset:

rd@h370:~$ pacmd list-cards
0 card(s) available.
rd@h370:~$ aplay -l

Any idea or hint is welcome.
