Fox that wont give you full 5.1....
I think he needs all 3 cables to be hooked in not just one. You need the Green, Black, and i think its orange??? At least for me thats what i have in the back of my PC.. ID be interested to know if anyone has gotten all 3 of those plugged into there tv also since i would love to do that. Im able to just plug the Green one into my pc but only a few speakers work properly from that. My tv a 42 sony braiva has a sound input on the back but the only adapter i have allows just one connection.
Someone probably has an answer to this!
