if you are running win2000, you are out of luck. the drivers in win2000 don't support 4-speaker mode
if you are running 98 however, you need to download the latest drivers from www.vortexofsound.com , and make sure you have the little control applet running in your tray. there is an option there to set 4-speaker mode and a little button to test the balance and fade.
i had a vortex 2, i loved the a3d 2.0 in half life, but after installing win2000, and finding out it didn't work at all, i went out and bought a turtle beach santa cruz for $80, and i'm very happy with it.
