[iOS]AVAudioPlayer currentTime latency

I'm building an iPad app that needs to scrub a sound file using touch events.  I thought I could get away with using AVAudioPlayer by setting the minimum supported buffer size, using uncompressed audio, and setting the player.currentTime property in response to touchesMoved.  I hacked this into the avTouch example to test, and if I move my finger very very slowly, it does what I want... but if I move more quickly, I get silence until I slow down or stop the touch gesture.  Is there some other setting I can change that would allow the AVAudioPlayer to respond more quickly to changes in currentTime, or will I have to go to the Audio Queue API?

Thanks for any advice.
