Nvidia Geforce GTX 260 HDMI Out With Audio?

So, I got a Geforce GTX 260 with HDMI Out Via a DMI Adapter.
But, in order to have sound on that HDMI output, I need to connect the card to an S/PDIF output on my motherboard.

My motherboard is an Asus GA-EP45-UD3L, and I do have an S/PDIF output on it.
However, I do not have the cable needed for it, so I'm just asking if anyone could perhaps direct me to the kind of cable I need, perhaps a picture or something. As I am not sure.

Thanks in advance!

P.S.
Sorry for my English.

Nothing fancy or special about it, in fact if you have a enough unused front panel wires and connectors you can make your own,

If you don't have enough spares at least it gives you an idea how easy it is to make one.

If you do not feel comfortable, here are others options.

I think you can find some cable already made on ebay.

If not then my suggestion is find a local/independant electronic store and a technician will make a cable for you. Most of them know how to do it.

If not then follow the advice given above, it will also work.

Thanks!

One thing I forgot to mention, that cable should have come with your video card. Might be worth contacting the card manufacturer and see what they have to say (from what I have seen most that didn't get the cable and contacted the manufacturer got one sent for free).

Pretty sad when an advertised feature on an expensive part doesn't work because the manufacturer cheaped out and didn't include a 50 cent part.
