Recently I noticed that the in-game sounds are not working. Everything was on in the settings but there is still no sound. Of course, this is not urgent. But I really like the in-game music and sound effects and would really like to know what is going on.
Is your device muted? Some devices have a mute button on the side that might be easy to accidentally enable. If that looks okay, try checking the sound settings within the game and the volume level on the device.
