hey all, just bought myself a nice 40" HDTV and got it hooked up to the pc, but i want to get the sound sent down the cable to the tv too. i have the Nvidia gtx 275 and the asus p6t dlx v2 mobo, now i know on the grpahics card to make it send audio i need to connect the 2pin spdif, but on the mobo theres only a 3/4pin audio connector. can i just connect to that or what? i use the onboard sound on the mobo.
