I have a 5.1 surround sound setup for my computer, which uses 3 headphone jacks to hook into the surround sound soundcard. (one for the front, one for rear, and the other for the center and sub) Is there a way I can hook these speakers into a reciever so that i can use them with my tv and xbox? I have yet to see a reciever that accepts plugs like that, all of them are just setup for speaker wire to plug directly in. Any ideas?
