Where is the sound enhancer on htc windows phone 7?

So i heard the app "sound enhancer" for htc wp7 got booted from the marketplace and into the settings on the phone but i couldnt find it. Anyone know how to enchance the sound on the htc wp7 ?|||The Sound Enhancer was causing Zune lock-ups on Mango devices. It needs to be updated for Mango, so HTC has pulled it off the market until they update it.
