I am trying to set up my system so that i may have surround sound from my tv through my Bose 321 system. My tv is a 56" Sony Wega KDF55WF655. My receiver is the Bose 321 system and I have a standard digital cable box. I know I have several options for setting this up but I am so confused at this point I dont know which way is up. I am using the standard connectors with the colored tips. I do not have any of the optical connectors. At this time I am not hooking up my HDTV. Someone please help me!!!
