Ok so here's the deal. I have my Asus Essentio Series Windows 7 Home Premium computer hooked up to my Sony Blueray 5.1 Home Theater Surround Sound System Model BDV-E570. It's connected through Toslink and I wanna play my movies through the tv. While the display isn't a problem because I'll use VGA, I can't get any sound! Why is this? I hook my toslink up to my Xbox and I can hear it clearly and perfectly and it comes up through Dolby Digital II LCM surround sound on the receiver's box text, yet when I connect it to the computer through the optical input in the back I don't even get any recognition. The Realtek HD Audio Manager doesn't say anything or help. What can I do to fix this?
