If it helps i'm only using an hdmi cable(1.4a), which worked with my intel igp, to an lg 42 lcd tv screen(also worked with intel) latest drivers installed.
in control panel> sound > playback i can select it but the configure button is greyed out as well as the set to default option, even test is greyed out.
The cable is plugged into the video card's hdmi port. (surprised no one asked.)
Do i need an hdmi 1.3 cable? i know 1.4 is supposed to backwards compatible but i never believed in that crap.
