Realtek ALC662 six channel audio chip. See page 36 of the manual.
This significance is that ALC662 (in addition to being six channel) does not provide content protection as does the
ALC889, and without a content 'protected audio pathway' Blu-ray sound may be down-sampled.
*No* ATI/Nvidia solution has a proper "protected audio pathway". Only S3's Chrome 530GT ($45 from their site) does that... But unfortunately no current software can take advantage of it either, and automatically downsamples (see below).
What that means is (1) you can't bitstream lossless surround codecs to your receiver, and (2) all surround PCM is downsampled to 16 bit/48K (which is CD quality+, but many Blu-Rays now are 24 bits and 96K). This is independent of whatever Realtek chip is on the mobo, because that is bypassed entirely for HDMI audio (the 8200 has its own audio circuitry on board for this).
You *can* get nondownsampled surround PCM on the 8200 by ripping the soundtrack and sending it as high-def FLAC, but this is pretty much the definition of "gigantic pain in the ass" (unless you are a stealing piece of shit). Basically, buy a standalone player for now -- HTPC tech is at least 6 months -- probably more like a year+ -- away from maturity for this stuff.
