Can someone help me out? i tried to use both of my front (green) and rear (black) audio port to play my music. I am currently using windows 7, 32bit. When i plug my logitech speakers to front(green), and altec lansing to rear(black), only the front speakers gave out sound but not the rear. I have changed my speaker configuration to quadraphonic but still doesnt work.

Later on, i tried one speaker in front port (green) and another one in center/subwoofer port (orange). I used the speaker configuration to test the sound and clicked play. All speakers (2 satellites, 1 subwoofer for Logitech, 2 satellites, 1 subwoofer for Altec lansing) gave out sound. However when i play music on Itunes or Windows media player only the front speakers gave out sound...

Looking online others speakers work on both front (green) and rear (black) speakers when plug in...
Can any one guide me?



Thanks alot! cheers!
