I have an hp pavilion tx 1000 laptop running fedora 7.  The auto
detect feature of the snd-hda-intel dirver doesn't work on my sound
card.  As requested in Documentation/sound/alsa/ALSA-Configuration.txt
I am forwarding the following to the developer mailing list:

alsa-utils.x86_64                        1.0.14-0.7.rc2.fc7     installed

With no options I get the following log message and the audio doesn't work:
 kernel: hda_codec: Unknown model for ALC660VD/ALC861VD, trying
auto-probe from BIOS...

When loading the module as follows, the audio works:
modprobe snd-hda-intel model=3stack

I believe the card was detected as 3stack-dig, as the alsamixer
options match when either no option or model=3stack-dig are given.

Hope this helped.

Thanks for all your hard work!
