Help with dolby soundstorm and logitech 5300e

Setup as in title, The sub wolfer is playing thought the center channel and the center is playing thought the subwolfer... every thing is all messed up it seems.. But every thing is connected right and set on 5.1 surround. Any ideas

Is there an option in the sound card's control panel for "center/subwoofer output swap"? The auzentech cards and turtle beach cards have this in their control panel but I've never had to use it. Look around and report back your findings.
