I have a eVGA 9600GT SC (512-P3-N862) 512MB video card and it seems to have a 3 pin S/PDIF out connector, in order to route the digital audio over the HDMI cable. I have contacted eVGA and this cable does not come in any 9600GT boxes, nor do they sell it separately. I am not requiring this cable now but would like to get this at some point. eVGA support suggested searching the Internet but that mostly find the larger digital cable for CD Rom. Where can I find the this cable?
