I'm new to home theater and I currently purchased a new set up for my bed room and need some help with the wiring. I bought a Sony KV-32HS420 and for the sounds I bought an Onkyo HTIB (S770). I also have a Playstation 2, an Xbox hooked up with the High definition kit, and a cheap DVD player for the time. I will also be purchasing a DVD player that supports HDMI in the near future (as soon as my Best Buy reward zone money comes) Before I go out and buy cables I just wanted to clear a few things up so I don't end up returning things. The Reciever for the Onkyo has 3 optical in's and I'm kind of confused on what to do. All of my equipment has Optical outs (TV, Xbox, and DVD player) but I would rather run the video cables right to the TV. I see no reason to buy more cables to run from the reciever to the TV when the TV already has the connections I need. I guess my question is, will only be running the Optical cables to the receiver work? There are no options to switch to the digital sound only that I can see. I want to get this set up so I can start enjoying my new set up. Please let me know what kind of cables I need to buy. If this is confusing let me know and I'll try to explain myself better. Thanks.
