Enabling sound caused some headaches. I finally ended with kernel 2.6.24 
and alsa 1.0.16rc1. The card was autodetected as Realtec ALC268, but no 
sound output.

Using  option model=toshiba instead, when loading the snd-hda-intel 
module did work, but sound has a really poor quality, with lots of 
crackling noises. Enabling the samplerate plugin didnt help...

Please let me know, if this card is already supported and I just have 
errors in my configuration, or further informations are helpful for 
develepment.


Thanks,
Phil
