Sound Problem

I’ve built this computer, and just about everything went smoothly…. except for the sound.
When I plug my headset into the front of the computer the wrong are in the wrong ear (eg on CSS if someone to the right of me is shooting, then I get the sound in the left ear, and vice versa). Is there anyway of swapping them so that they are the right way?
BTW I can’t turn my headset around as it’s uncomfortable, and yes if is the right way round to start with
I’m using Vista Ultimate 64bit
Any help would be appreciated.
