Theres no sound!!!!

I really hope the makers of this game are reading these comments. I used to have this game on my iPod touch until I got my iPhone 5C. Now the songs/sounds dont play on this app. If anybody has any tips or has been experiencing this problem plz comment to show them they need to fix this!! Also if anyone can help me out and tell me if you can access options in this game plz tell me! It would be greatly appreciated.
