M-Audio Revolution and subwoofer powered speakers

[liquid_cool]

Is anyone familiar with the M-Audio Revolution sound card? I'm having trouble because I have speakers where the satalite speakers are powered by the subwoofer, the sound card has plugs for Front L/R & Phones, Center/Subwoofer, Surround L/R, Surround Center L/R, and Digital Out...
My problem is that the other speakers are plugged into the subwoofer, and then one line comes from the subwoofer... If I plug that line into the Center/Subwoofer, the Subwoofer works but the other speakers don't, If I plug it into the other speaker plugs the speakers work right but not the subwoofer... is there any way around this?

One line from the sub? If so the speakers are probably digital and need to be plugged into the digital out of the sound card.
