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:
#uname -a Linux laptop 2.6.21-1.3228.fc7 #1 SMP Tue Jun 12 14:56:37 EDT 2007 x86_64 x86_64 x86_64 GNU/Linux

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!
