tx1000 audio

According to http://ubuntuforums.org/showthread.php?t=442483, to enable audio in a tx1000 (00:10.1 Audio device: nVidia Corporation MCP51 High Definition Audio (rev a2)) you can add

options snd-hda-intel index=0 model=3stack position_fix=0 single_cmd=0

to /etc/modprobe.d/alsa-base

I did it in my tx1110us and it worked just as expected with ubuntu 7.04, kernel 2.6.20-16-generic, 64bit.
