I am trying to use a Via VT1708 audio card ( uses the snd-hda-intel.ko driver) to record from SPDIF-in.
An off-list reply to my posting to alsa-users list suggested that snd-hda-intel.ko might not support SPDIF-in with the VT1708 card, which brought me here.
Can someone who works on the Intel HDA driver tell me if it supports SPDIF-in on the VT1708 audio card?
It should be, but not tested well, I guess.
The driver enables the SPDIF-in capability when BIOS sets the pin information properly. Check /proc/asound/card0/codec#* file whether you have any (activated) input pin node that supports SPDIF-in.

Thank you for your reply! The output of your command is below. spdif-out=Node 0x25 spdif-in=Node 0x26 Neither labeled inactive, but spdif-in doesn't list a "Connection" line.
Just because it's only for input (thus it has no "source").
I have the latest bios: 1.03 (2007/08/23) (a beta bios is available). Do I try the beta bios?
I don't think so. Likely a driver bug. How about the patch below (against the latest HG version)?

After making the changes by hand the compile failed.
The problem is irrelevant with my patch. The build looks broken on your system anyway.

The configure doesn't check properly from here on. Check config.log. You must have relevant compile error messages.
