I am just wondering how you repeat a AVAudioPlayer?
From the iOS docs:
numberOfLoops
The number of times a sound will return to the beginning, upon reaching the end, to repeat playback.
@property NSInteger numberOfLoops Discussion A value of 0, which is the default, means to play the sound once. Set a positive integer value to specify the number of times to return to the start and play again. For example, specifying a value of 1 results in a total of two plays of the sound. Set any negative integer value to loop the sound indefinitely until you call the stop method.
Availability Available in iOS 2.2 and later. Declared In AVAudioPlayer.h
