Currently I have a Logitech system that uses green orange and black 3.5mm plugs. I have a sounds card to utilize this for my PC, but I'm now wondering if there is a way to stream the PS3 sound in 5.1 surround sound with the same 5.1 speakers. I've looked a little at receivers and it seems like you need something that can handle the 5.1 technology. I'm looking for a cheaper option possibly. What are my options for doing this? Could I stream the tv audio to my PC and just run it from the pcs speakers? Or do I need some type of receiver + splitter?
