All,
I was having a problem with my HTPC not outputing more than PCM stereo regardless of the source or settings. This may be specific to the above MOBO, with the Realtek 1200 chip, but here's what happened and how I fixed it...totally not intuitive.
The device labeled "Realtek HD Audio (optical)" put out over the phycial coax connection on the back of the MOBO. The other device labeled "...Digial Out" put out over the optical, so they were basically reversed in the driver. Once that was figured out, the DD and DTS tests in the driver correctly passed to the receiver, however, no DVD, BD, or HD-DVD content would pass. I only got PCM stereo.
Long story short, I tried about everything. The fix came when I went into the BIOS and changed a setting that is for an internal SPDIF header. There is an interal SPDIF header to output "standard SPDIF," or "HDMI SPDIF." Now, I did not even have anything hooked up to that internal header, I was using the built-in backplane connectors. It's used for connecting either an add-on optical or coax jack, or routing through an HDMI/DVI video card for pass through. The defaut setting was standard, however, once switched to HDMI, it would correctly pass DD and DTS through the backplane. Problem solved.
