Have you got a link to your specifc GPU? fomr what i can see it onlyy has DVI.
Also have you got teh audio connected to the GPU, or are you tryign to get it through the pcie slot?
Here is the link for my GPU http://www.tigerdirect.com/applications/SearchTools/item-details.asp?EdpNo=3123171&CatId=1560 Looks like this link does not work. Google "xfx 7600 gs hdmi" and click on the "tigerdirect.com" link.
I have the HDMI cable connected to the GPU's HDMI slot and connected to my Panasonic Plasma HDTV.
The GPU uses a PCIe 16x expansion slot. At this time, I have a sound coaxial cable connected into the GPU coaxial "in" port and the other end of the coaxial cable is plugged into the coaxial output on the rear of the MB; as described in the setup manual for the GPU.
My OS is Windows 7 Home Premium Edition. No updates except the latest driver from Nvidia for this GPU. I tried using Intels auto driver scan but it shows white space where driver updates would go. No othe software has been installed on this computer.
Checking with Device Manager or the sound mixer, I do not see anything relating to any of the SP/DIF devices onboard the MB. I can get sound out of the front headphone plug and through the speaker plug into the lite green colored "speaker" port on the backside of the MB.
I have excellent video output over the HDMI cable but no sound.
Thank you Cpt.Dogfruit for your assistance.
