Help with blue-ray player

Hope you can help. My husband has been working on this for about 10 hrs now. He has a Sony SiliconX-al Reflective display TV KDS-50A2020 and a Pioneer Audio/video muti-channel receiver, VSX-84TXSi and a Panasonic DMP-BD10A blue-ray player. All have been connected and reconnected in multiple configurations in hopes of getting all this (black boxes) as I affectionally refer to them to work. He gets a picture but can't get any sound to come out through the surround sound speakers. He can get the sound to come out from the TV. But nothing through the surround sound. He even has those expensive cable connectors and nothing and I. Do mean NOTHING appears to make these rather expensive boxes to work. Can you please make them work? If need be you can contact him here at our home (732)370-8625.
