I have set up an AVAudioPlayer object in viewDidLoad, as per the Apple guidelines, calling prepareToPlay as the last line in viewDidLoad (i have tried in awakeFromNib also).

When i press my play button, there is a pause, as it would appear to load the file, then it plays.

In audioPlayerDidFinishPlaying, i reload the player with a different sound, and when clicking play for a second time, the file plays instantly.

What would cause the player to lag on the first play?

Thanks.
