Great game, lots of options but sound does not work on iPad – Airport Mania 2: Wild Trips Review

I cannot get the sound to work at all (sound fx or music) on my iPad. Currently my ipad is running iOS 4.2.1. Please fix the sound because I really enjoy the game but I can't hear when the helicopter is coming or a plane getting "angry". Thanks.
