If the game is having problems playing sound, please try the following:

1. Check the game's settings to see if music and sound effects are on.
2. Restart the game.
3. Restart your device.

That usually fixes the problem. If the sound is still off, please try the following:

1. Make sure your device is not muted and that the volume is up high enough.
2. Try plugging in and unplugging your headphones.
3. Make sure your music player is turned off.

If none of the above works, open another app to check if the sound is working there. If not, the problem likely has to do with the device itself rather than the game. Please contact the manufacturer for further instructions.
