The stupid question is how do I know if my soundcard will support 5.1? When I go to see what type of card it is it says "SoundMAX Integrated Digital Audio." The instruction manual talks about 2, 4, 6, 7, 8 channel sound cards. All I know is that I have three jacks on the back of the computer, the blue, pink and green. So far I can only get the "front speakers" to work (not the rear or center).
