[Sound 5.1 not right]

I have just installed ARMA II and found that my sounds is not working correctly in game.

I hvae checked the Window vista x64 setting and used the test button to make sure the sound come out of the right speakers BUT! in game if someone is shooting in front of me it sounds like the gun shots are coming from behind!!? :confused:

I have reinstalled the drivers;

Checked Windows settings; (Front Left/Right, Centre, Sub, Rear Left/Right)

Checked speaker cables;

Has anyone else had this issue? now how to fix this issue? etc
