Some Sound Advice

No really. I can't seem to get my sound to work. I am using the sound card that came with the MOBO. Supreme FX I believe. The device manager says it is working properly but no matter what jack I plug into I get nothing.
My connectors on my Altec Lansings are black, yellow, green. Naturally they don't tell (the connectors) where they go. The sound card ports are (in this order)
Grey= side out
Black= rear out
Orange= cen/sub
Pink= mic in
Green= front out
Blue= line in
They don't make these speakers anymore so I couldn't get any info as to what wires are what. I took the Audigy out of my Dell but it's AGP. The speakers work fine with it in the Dell. Not sure what to do at this point. Any ideas?
