Madden 08 through HDMI problem

Hey everyone, getting a bit frustrated here.

So over the weekend I upgraded to the ATI 4850 video card. I have my PC hooked up to my TV/Surround Sound, so I've decided to utilize the HDMI capability since I also watch hd-dvd/blu-ray on the PC. I have a lot of games installed on my PC, and EVERYTHING works fine, outside of Madden of course.

The problem I'm having is that the only sound I am getting in the game is the menu music. I don't get menu sound effects, or ANYTHING in the actual game. It's total silence. And when the HDMI clicks over on my receiver, I get the "no signal" message, where at least I get something while I'm in the menu. As I've said I have a ton of other games that I play (MVP 2005, Bioshock, Crysis, Oblivion, Morrowind, Orange Box, DMC, list goes on,) and all of these games work totally fine, just as they did before I used HDMI for my audio.

Does anyone have any ideas? Is there something out there that could potentially solve this problem for me? I know Creative Labs made that Alchemy program that helped with legacy sound over digital devices, but that is only for the X-Fi/Creative labs products. Any help would be greatly, greatly appreciated.

Hm, interesting. It probably is something similar to that, I'll have to mess around with the Windows sound settings tonight and see what I can come up with. Maybe changing my speakers from 5.1 to 2 speaker stereo will fool it into working. I'd have to remember to do something like that every time before I play but hey if it works, it works.

Thanks for the tip.
