Did you follow the instructions for 6-channel audio on page 64 of your manual? Have you installed the HD drivers from the motherboard utility disk?

Interestingly, I recently set up a different Gigabyte board that refused to play the rear speakers with a 4.1 system (no center). In order to get the rear channels to work, I had to configure the speakers in Control Panel as a 7.1 setup, then simply disabled the unused channels.

Does it have an SPDIF output or just the standard jacks?
