[alsa-devel] hda_intel: SPDIF not detected on Asus P7P55D PRO

Fri Sep 18 05:38:04 CEST 2009

I just set up a new system running an Asus P7P55D PRO motherboard. It 
looks like this uses the VIA VT1828S codec. The analog output seems to 
work but the SPDIF output isn't recognized. Originally tried 2.6.30.5, 
but Linus' current git doesn't seem any different. The device only gets 
detected as HDA Generic, which, from my reading of the code, ignores 
SPDIF outputs. I tried hacking patch_via.c to add the codec ID to match 
existing types like VT1708S and VT1702, each of those got the SPDIF 
output to show up, but no output showed up on the receiver, and also the 
analog output then stopped being recognized (looks like some node IDs 
don't match).

Is there some extra support that needs to be added for this codec, or 
anything else I can try to get this working? The SPDIF does work in 
Windows 7 with just the standard Microsoft HDA driver..

The codec data seems to have references to the SPDIF output, but no 
device is actually getting created. The data is below. Any suggestions?
