FYI, for anyone checking this in the future, I was contacted by someone who
said this does indeed work.

In addition, I found that a client of mine had a machine with this
motherboard and I was able to check it out using Knoppix (5.1?).  It worked
without hassle (just had to unmute the IEC??? in alsamixer).  Dolby Digital
passthrough worked perfectly via mplayer.

In addition, my comment about the ALC888 was incorrect.  Firstly, it was the
ALC883 chipset that I had problems with, and after upgrading to a CVS
version of 1.0.14 (post-1.0.14 final release), it did work (Dolby
passthrough via the ALC888).

Can anyone tell me if the ALSA driver for the STAC9271 or STAC9271D
supports Dolby 5.1 passthrough via S/PDIF?

I have only limited experience with this, but I wish to build an HTPC with
Linux.  I've played with an HP Slimline s3120n (ALC888 chipset) which has a
coax/RCA digital out.  I was able to get sound working, but couldn't get AC3
passthrough to work for the life of me.

I wish to avoid that experience.  I'm possibly looking at an Intel DG965WH
motherboard. ( http://www.intel.com/products/motherboard/dg965wh/index.htm)
If I am reading this right, I can get the STAC9271D chipset with S/PDIF
output.

Any help or experience would be appreciated!
