Hey guys, I was wondering if it was possible to do a 4.1 surround setup for my pc. The thing is I currently have a 2.1 (2 speakers and 1 sub) setup, but I have a spare speaker set (2 speakers) that I want to use. I currently use a Dell xps1530 and it has two audio out ports. So I was wondering if I could plug both ports in and have a 4.1 (4 speakers and 1 sub) setup?
