Asus 9600GT audio passthrough

Does anyone know how the audio passthrough works on the Asus EN9600GT. I just bought one today and the card has two DVI ports, a DSUB port and an included DVI to HDMI connector. I'm not quite sure how/if the audio gets out the DVI port on the GPU.

You connect a SPDIF cable from the sound card/motherboard to a place on the video card and it passes through the dvi-port/HDMI adapter and through an HDMI cable. If yours didnt come with an SPDIF you need to buy one.

I didn't think DVI could carry audio. Is the DVI to HDMI connector which came with the video card a special one?

DVI cannot carry Audio, but HDMI can, and thats the only difference between the two. I know that ATI cards have a built in audio device on the cards so that when you plug in an HDMI adapter, you get sound in the HDMI, it might be true for this card as well (not sure about it being onboard though).

You are correct in that a DVI cable cannot carry audio. I think the adapter is special in that it uses some of the pins normally reserved for analog video (since DVI can carry both analog & digital video) to carry the digital audio signal. That's basically the only way to pass audio through to the HDMI cable afaik.

I guess if you had to you could always use a SPDIF cable in addition to the HDMI cable. It's not quite as pretty, but works the same.
