I cant figure out how to get my new i3 system to output more than stereo. Im starting to think its a problem with the AVR.

H55M-USB3
i3-540
Win 7 Home Premium
Connected with HDMI to an Onkyo SR-TX606

It says PCM on the AVR and it seems windows knows it is connected to it but only gives me the option for stereo. I have reinstalled the Intel driver and it did not help. Is there some driver I need to get to allow 7.1?
 
Sounds like the HTPC is trying to process the sound and not passing it thru. I used Sharks Codec Pack and told it to skip AC3Filter, passthru and not to touch the speaker configuration. Then you would have to setup Windows that you're at 5.1 or 7.1 or whatever. Then there was some small tinkering with FFDShow's audio setting. Sorry I can't find a link explaining that better atm, at work and all.
 
Have you tried downloading the newest Realtek drivers from Realtek's site?

You don't want windows drivers taking over Realtek's drivers in this case because you won't get 7.1. That would be the first place to try. (I have had to do this fix for a bunch of systems with ATI cards in them)
After you do that the best way to test the system is to pop a DVD in and see if it plays with 5.1 sound.
 
The OP is using HDMI though, Realtek's soundchip isn't being used at all it's all. The Intel GPU passing it thru til it hits something that knows how to play it, that being the receiver. I never bothered with the junky Realtek driver on mine since I was never going to use the sound outputs or even the SPDIF.

I'm staring at some XP workstation so I can't click on it to verify. There's the wizard-ish program you have to open and tell Windows how many speakers you have. Also I had to change the output from default (which I assume is realtek?) to some mangled name of my receiver, which in my case was SONY-AMP-123something.

It does work for my anyhow. I'm using the same list as the OP, Media Center and the Shark Codec installs with audio passthru selected. I can't find any of the guides I used in Google and I'm very limited to what pages I can see at work so I apologize for that.

My bad. Next time I will try and read the entire post rather than skim. If you can not get the HDMI audio to work though it can always be a fall back option. (although not the best option)

Numan's suggestion with Shark's Codec should work though and would be the next place to start.
 
I'm just surprised I took in what I read for once seeing how I'm on my 4th coffee already :D
