Hey, I was woundering if anyone could help me out!!! I have just hooked up my surround sound to my computer and it works fine but the back 2 speakers dont work all that well. Sound comes out but its just back ground noise that you really cant hear anyways, I was woundering if I have to get a new sound card or whats the problem! I want all sound to come out equally of all speakers, just like a normal stero would, but istead of 2 speakers there would be 5 and a sub!!! Someone please help me!!!
