If the sounds in the game are gone, please try the following:
- Check the game settings to make sure sounds and music are turned on.
-Restart the game app or device
If the sound is still missing, try this: -Make sure your music player is turned off.
-Make sure your device is not muted and that the volume is high enough.

If none of that fixed the problem open another application to make sure the sound is working in general. If the problem persists, it probably has to do with your device itself rather than the game, and if this is not the case then we recommend you to contact our Costumer Support.
