making vista recognize headphones

hi

i am using a pair of turtle beach ANR20 headphones on the system listed in my sig. vista doesn't recognize the headphones as being headphones, but rather lists them as speakers on the sound CP (even though sound plays through the headset). normally i wouldn't mind much, but i can't apply any of the sound settings i want from my xfi software. any ideas on how i could get vista to recognize my headphones as being headphones?

HAd a look over Turtle beaches site and couldnt find any updated drivers for Vista, I'd suggest getting in touch with them via their support site and asking them if they have a workaround yet or not.
