I also have a Tyan S7025 motherboard with the Realtek ALC262 soundcard. I cannot
make it work. 

I have tried all the possible models for "options snd-hda-intel model=MODEL"
(including hp-bpc) in /etc/modprobe.d/alsa-base.conf. I have also tried other
options such as probe_mask=1, etc. 

I have reinstalled all the alsa related packages (Debian Squezee 64-bit),
compiled alsa from fresh sources and also from the sources downloaded from the
Realtek website. 

Finally, I have even upgraded the BIOS to version 1.05 (it was 1.03 before). 

Any suggestions?

Kind regards,
