iOS Problem with multiple sound buttons.

The problem with how the app is now is the first time you press any of the buttons there is a 5 second delay. After that no problem

I remember reading somewhere that when you play an audio sound for the first time, there is a delay. After that it all runs fine. I think the author loaded one of his sounds in the viewDidLoad method with the volume at 0 and then when he played another sound there was no delay. I'll try and see if I can find exactly where I read it and post it for you.
