A client has a video card with an HDMI output and for sound to pass through it, there needs to be an SPDIF connection to the video card. It is a two wire connection, meant to connect to jumper pins. The motherboard doesn't have an SPDIF connection so I bought a sound card that listed this feature, the Creative Labs XtremeGamer. However, I can't figure out how to connect the SPDIF wire pair from the video card to the XtremeGamer. I've not found the answer yet on a search. Any ideas?
