Sound from PC > TV through HDMI

[billjimbob]

I have a 9800gx2. From what I've read, I can receive audio through the card to my HDTV, which is connected via HDMI. Apparently, my card came with a 2-pin SPDIF cable that goes from my video card to a sound card (or onboard sound in my case, a 780i). However, I lost the cable (doh). I'm ok with just buying another cable, but I'm having trouble finding exactly what cable it is. This is the only image I could find of it:

Then I found this cable at Amazon:

Is this the right cable I need?
