I had/have this problem as well.
You have to change it in Vista by right clicking on the speaker icon in the
system tray->audio devices->Play Control->Configuration. Set it to 5.1
Then go to the Creative Audio Panel and set the speakers for 5.1 there as
well.
Works for me but I have to reconfigure it everytime I reboot.
