I went back to a fresh 32bit Vista install. After the install was done, I used the Asus InstAll utility to install the INF, Matrix, RealTek, Gigabit and G35 in that order. Once again, the sound worked when playing audio, video and DVDs with WMP11. I also found that I could change the number of PCM channels being sent to the receiver by going to:
Control Panel/Hardware and Sound/Manage audio devices/HDMI Device/Configure
Here I changed from Stereo to 5.1 Surround, verified that the proper optional speaker boxes were checked, and that all were set to full-range. Doing so changed the PCM channel count going to the receiver from 2 to 6. Despite this, the windows test tones still did not work, but at least WMP11 did reflect the change.
Next I installed PowerDVD, which came with my LG BD/HD combo player. I then attempted playback of a HD DVD, and got the error "Incompatible graphics driver". Then, after letting PowerDVD download the latest version, the error message changed to all familiar one about no HDCP support.
So a clean install, using the drivers that came with the hardware, all installed in the default order automatically, still does not seem to allow HD playback unless connected directly to the display, which defeats the benefit of having audio on the HDMI port.
I'm also quite concerned that Vista is so heavily involved in deciding how the digital signals are being sent to the receiver. I sure hope DT2 will have direct control and ignore whatever is set in the control panel for channel count and sampling frequency.
archibael, I will call Intel after the holidays if I don't figure something out in the meantime. I do appreciate all your help!
