5.1 Surround Sound

[kitch69]

Hey, I have just bought a set of new 5.1 Labtech surround sound speakers and were wondering if I would need to upgrade my sound card. At the moment I can only get two speakers working so maybe i need a better sound card? At the moment It says I have a C-Media CMI8738/C3DX PCI Audio Device. Do I need to buy a new sound card or should the one I already have work with 5.1 speaker set? PLEASE HELP!!

AMD Athlon XP +1600

According to the PDF Manual for the device...which I found with a Google search...this is a 4 Channel audio device.
