So, now that you have adjusted "Line Out" you have sound again, correct?

Then this might be easiest resolved by just adding a "Line Out" section 
to /usr/share/alsa/init/default that intializes Line Out to something 
else than zero. We probably should do that anyway.

Takashi, do you agree? If so I'll write a patch for it.
