hehe, yes. I didn't believe it either. This laptop has three jacks. 
 - light blue, symbol "headphone", normal 3.5mm jack
 - pink, symbol "microphone", normal 3.5mm jack
 - black, symbol line out, normal 3.5mm (that only goes in 2/3 of the way) 
jack AND SPDIF (yes, now glowing red)

Actually. Seeing is believing.

Thank you very much

Just hg'ed again compile runs fine.

This is without any "options snd-hda-intel model=XXXX" line 
in /etc/modprobe.d/alsa-base

 - I now put my headphone into the black jack and get sound, boxes turn off.
 - light blue jack is without function now. 
 - mixer option "headphone" is without function.
 - mixer now has master, 
headphone,pcm,front,frontmic,line,mic,micboost,digital
 - only master,pcm and front work, all regulate master volume on 
SPDIF-used-as-headphone-jack and the internal boxes
- dont have a mic right here to try out

Should I try options there now? Is /etc/init.d/alsasound stop / start a good 
way to cycle through options?
