Use the generic windows based audio properties to switch the audio device, as your GPU/Chipset (not sure if your using onboard or what) is also an audio device since it has HDMI.
Just pick the AMD HDMI Output when using the TV/HDMI cable and you *should* have sound.
AMD = ATI
Yea ill be using the HDMI right to the tv in the living room, its going to be connected to the back of my GPU. I'd rather not go optical as thats just another cable to be then hidden.
I do have on board HDMI but the Chipset is nothing near my GPU so that would suffice for films etc.. but not for gaming.
So does this GPU take its sound directly from the PCI-e slot on the mobo? If this is the case I should like you say get sound directly from the HDMI on my GPU, if not the AMD HDMI listed in the picture above im afraid will be the one on my mobo.
Sigh... Thanks for all your help but I believe the best course of action is to move the PC closer to the living room when the kids are in bed and use a 5m to see if I get sound then work on it from there.
