I need help on hooking up the xbox, to get 5.1. I have the reciever that plays it all. My component cable has a plug in for an adapter. So I have my optical cable in my reciever, then the other end goes into a adapter. The end of the adapter is just a gold pin that goes in the back of the component cable. But I am not getting 5.1 on anything. Is it the adapter? I don't understand how the gold pin can produce the optic cable signal? Do I need the HD pack? Or should I go out and buy the new Psyclone cables? The cables I am using now are the Monster cables made for the Xbox. Sorry if this is confusing, but believe me I am confused. Can somebody help me? P.S. When I switch the settings on the Xbox to Dolby Digital, I just get a buzzing sound out of the speakers.
