Nope, optical SPDIF, not Coaxial. I have tons of component RCA cables, but I need the Fiberoptic SPDIF cable. Uses a toslink connector. I think I found a Rocketfish one at Bestbuy.ca for $23.
That or I figure out how to pass sound through my ATI 4870 and a DVI - HDMI cable. I looked at my board, couldn't see any sound in connectors.
