9800GTX and HDMI to DVI Problems

I just got my eVGA 9800GTX yesterday and when I use my DVI to HDMI cable no matter what I do or what drivers I have installed my screen looks like it's running in 16-bit color (only after the drivers are installed) and I get the occasional white noise through my monitor speakers depending on the driver versions even though my PC is plugged directly into my receiver through a single optical cable. Thankfully the resolution/scaling looks normal it's just the picture quality that is unforgivable.

I had an eVGA 8800GTS(G92) before this and it worked perfectly and then while I was waiting for the 9800 to get here I was using an eVGA 9600GT which had the same problem when I was using the left DVI (when facing the back of the tower) but the right worked just fine, with my 9800 both inputs have this problem. I have tried all the compatible drivers nVidia offers and some from Guru3D with no change. Right now I am using the VGA connection which looks fine but I need that open for other components. Any one have any Idea if there is a fix for this or am I at the mercy of Nvidia's Engineers and Programmers.

Specs:
Vista Ultimate 64bit (Service pack 1, everything up to date)
Westinghouse L2410NM (24" Monitor)
Hiper 680w Type R-2
ABIT IP35 Pro (BIOS up to date)
Intel E8400
2x2GB DDR2 1066
eVGA 9800GTX (Driver version 175.16)

So not a single person here has run into this problem or knows anything about it?

Hey, check this out. We've been working on this problem over on the EVGA forums and this fix really works. http://www.evga.com/forums/tm.asp?m=329821
