I have a Sweex 7.1 sound card (http://www.sweex.com/SC015) which has a 10 pin (one missing) header for optical in/out. ST Lab has the same card as well (http://www.st-lab.com/products.asp). The 10 pin header is similar to the 10 pin S/PDIF header on an Audigy 2 ZS although the pinout is not the same. Does anyone know which pin is the S/PDIF out and which are ground pins? I'm looking for those two pins so I can attach the S/PDIF cable from my GF9600 GT to them. I currently use two cables more or less taped together (one end coaxial and the other the S/PDIF cable that came with the videocard). It works perfectly but it looks a bit messy. Using the header pins would be the better choice.
