I am coming here for help as I have tried everything possible to get Dolby Digital sound to play my games in.
Custom built desktop with AMD 965 BE Quad Core, Asus M4N98TD EVO motherboard, eVGA GeForce 470 Superclocked graphics card.
The motherboard supports native 7.1 and has it's own Digital Coaxial & Optical outputs.
The graphics card carries up to 7.1 via HDMI. I am running my graphics card HDMI output to my Samsung 40 1080P LCD.
I have tried just running HDMI to my TV, then using the Optical output from the TV to my receive, as well as running the optical output from the motherboard directly to my receiver, to no avail.
In the Windows sound option, I have enabled Digital Audiot S/PDIF. When I click Supported format, I see Dolby Digital and can hit test, at which point I see my receiver switch from ProLogic / Stereo to Digital, however sound only comes out of my front speakers as if it were in Stereo.
Under Advanced Tab, it only shows 2 channel options. If I right click on Digital Audio (S/PDIF) there is no 'configure' option, where I could select the speakers.
This really bothers me, since when trying to play all my games, i.e. Battlefield 2 Bad Company I can only get Pro-Logic.
This should be much more straight-forward, but I can't for the life of my figure it out.
Any help is greatly appreciated!!
