It might be problematic to get my ad700 sold atm..... Anything I can do involving the card itself, maybe a custom driver or something?

Not sure if anyone can help me, but I recently bought a creative Soundblaster Z, and the sound is extremely loud even on the lowest volume ( Highest I can go is around 20% before it becomes uncomfortably loud ) . After doing some research I know that it is due to my headphones (ad700) being low...
