hello, well im not sure how this works..i had an audigy 2 zs installed and connected to an home theater receiver, sound works fine. I noticed there is a toslink connection in the back of the motherboard which say its comes in hd. so i tried connecting a toslink to my receiver but there seems to be no sound, or even sound device found. It seems the driver is installed, but the sound manager for realtek give me and error something like that. Am i missing the point of this toslink? and how would i go about using the toslink to digital sound? Thanks in advance
