Only getting 2 channel audio?

[Wogzillar]

I wonder if someone can help? I'm only getting stereo sound. As in left and right channel when playing the game. I've tried with two different sound cards on two different 5.1 systems through analog AND digital, but only ever have sound L and R?

Obviously before anyone asks, I tried lots of other games and they all work fine. Is anyone else having this trouble? Or is it just the way the game is made?

 

Thanks for any help

I have Creative Sound Blaster Z and 5.1 sound works fine for me.
