I'VE GOT NO SOUND
Note: From my experience, all sound issues come from the side switch that can be used to mute sound or lock rotation.
This is a frequent issue due to the strange way this switch works.
Some of our apps use the iPad side switch (or iPhone silent switch) to turn sound off, so the issue should be related to this switch.
So first check if this switch is not enabled (the switch is located next to the volume buttons, and the orange should not be showing).
You can also check the volume buttons.
Note that the side switch does not mute Media Playback but only alerts, notifications, sound effects, and app audio
- so your may think that this is the app that has an issue but it is only related to the side switch.

We've also seen a bug where the sound will stay off if you change the Side Switch to "Lock Rotation" while the iPad is Muted:
Here's the solution to this issue:
• Make sure the orange dot is not showing on the Side Switch on the upper-right corner of the iPad.
• Go to Settings > General > Use Side Switch to: > Check Mute
• Open the app, and the sound should now be working (if not, try to use the volume button)
• (Optional) Now if you want to change the Settings to “Use Side Switch to: Lock Rotation,” you can. With the Lock Rotation setting selected, you can change the Side Switch to show the orange dot, and the app will now still have sound (but do the changes when iPad is not muted)
For other issues, you may try to restart the app, or reinstall the app (reinstall is free, you won’t pay the app again).
