I have a Sony BDVE500W Blu-ray Disc Home Theatre System with a Panasonic Plasma HDTV (TH-50PZ80U-A). I have the following equipment that want to connect to my receiver so I can get 5.1 surround sound through my TV: XBOX 360 & mac mini (latest generation). Below is a screen shot of the rear panel of the receiver and need your help to come up with the right configuration. I have my mac mini connected through an RCA cable to the TV and the xbox through component. The TV is connected through an optical TOSLink to the receiver (there's only on IN TOSLink on the receiver). The xbox gets amazing sound through the receiver but the mac gets no audio (note that mac mini is connected through HDMI. How can I get my mac mini connected to the receiver, along with my HD cable box, TV & XBOX? What am I missing? Thanks.
