Audio problem

I used to have this game on my iPhone 4s, and it was one of my favorite games, one I could play over and over. Now that Ive upgraded to the iPhone 6s however, I noticed that there is a tiny problem. The game works properly as it should, no glitches and it never boots me out, but theres a sound issue. After activating "dream time" the sound effects and background music goes completely silent. Only after "dream time" does the background music return, but sound effects are still MIA. No sounds from Alice or picking up coins can be heard until I exit the game and reboot the app. Its a bit disappointing, I used to love listening to the sounds of all the coins Id gather in dream time, but now the game is a bit dull. I noticed that the app hasnt been updated since 2013. Its going to be 2016 soon, and people are getting more updated versions of iPhone. I used to really enjoy this game, and I could easily see myself downloading this for every new iPhone I get, but the sound problem is dragging it down. Hope this can be fixed, so future users dont have the same problem. Thank you.
