No SFX during solo

My iPad Air 2has no sound in solo mode … Is there a bug fix for this?

What are your device volume settings. Did you accidentally mute your device?

Is the Volume slider fully up in the “Audio” panel of the Settings?

All volume settings are okay … Other apps are working fine

No engine sound?

I have no sound at all … I have re installed the app yet still no sound . Other apps still working properly

What iOS version? Is the iPad Jailbroken?
Did you check to make sure the volume in the Audio settings are turned up?
Also what happens if you try with headphones?
