Most games would typically have their own volume controls. Since the 
"Creative X-Fi" driver has hardware-accelerated OpenAL, it bypasses the 
Windows Vista/7(/8?) audio service. Since the audio service doesn't see 
the app, it can't handle the volume controls for it.

Without the driver providing global volume controls, it needs to be 
handled individually by each app.

Is it possible the game provides keybinds to raise and lower its Master 
Volume control? That would be a game-specific thing, but I'm not sure 
how else it can be done while using hardware-accelerated OpenAL.
