Hi Clemens ,

I tested your solution and here is the result:

1 - Keep my changes in sound/pci/hda/patch_via.c + your solution ----> 
The kernel did not crash + alsamixer showed the full interface, but the 
there was no sound, after rebooting the system, I had sound.

2 - Only your solution ----> The kernel crashed ( always ).

Maybe I am still missing some more settings in 

What do you think Clemens?
