So the front output off the sound card is not working then, Correct?
Have you gone into the speaker setup and set it to just desktop speakers - 2 channel - to see if they work?
Have you tried reinstalling the software for the sound card?
you probably did this, but check the connections, from the sound card to ur speakers, it could be that ur front speakers aren't actually connected
what i mean is, the front speakers could have a seperate mini stereo jack connection from the back ones, just check that those are conneted correctly
If ur using a digital connection, ignore everything i said
Lets go through the stuff i already tried.
I updated the drivers,
I'v set 4 speakers setting @ at the Audio HQ (part of Creative drivers),
I tried disconnecting the rear speakers, and the front began working.
I'v tried switching connections (connecting rear instead of front and vice versa) and that caused only to front speakers to work.
I'v tried setting a Quadronic settings at the windows Speakers Settings,
However after each time i restart the pc, it seems that the setting is going back to default
