The DVI/HDMI adpater is also special with these unused pins. they are connected to the corresponding HDMI pins so that you can have video and audio through HDMI.

What I don't understand is how you are able to get full LPCM with the ATI cards. Don't they use a SPDIF cable to connect to your audio card? I thought that you couldn't us SPDIF for LPCM, DTS-HD MA, or Dolby TrueHD.

No - they dont. Neiter does the Nvidia 9300/9400 and 8200/8300 series motherboards. The Intel G45 chipset also delivers 8 channel LPCM. ATI,Nvidia nor Intel will bitstream - they take the converted DTS HD MA or TrueHD signal and deliver it as LPCM like the PS3 via the HDMI cable. If you use the analog cables - its still lossless - It does all of the steps in the PC and sends it out over the 7.1 cables - like a Standalone with 7.1 analog-outs - HTPC is a big learning curb for the novice - but great for the experienced user
