NO 5.1 output on ASUS 5750 with no compressed formats supported (Win7 x64)

[jlzhisname]

I am running Windows 7 (x64) I can not get HDMI on my ASUS EAH5750 to output 5.1 passthough for compressed audio formats (no DTS, AC3, PCM or DD). as per ATI's site this care supports output of AC3 PCM and DTs and passthrough of the HD DTS and HD Dolby formats. These formats are not available in the ATI HDMI output device's options. I only have 2 channels and no compressed formats available for output.

Please assist if you can. This has me pulling my hair out!

I have a dell with an onboard Realtek ALC888. I am getting conflicting reports as to if I should disable this function in bios. I have it currently disable as ATI says the card can output these formats natively.

I have tried many recommended methods to get this to work and so far no luck!
