I use an iPad 2 and my music plays, you tube plays also but keyboard games and all other sounds are mute. I have tried virtually everything: restarted, reset, slide lock, double clicked home page and ll... But still to no avail.. Can some1 please help
Don't worry. Lots of folks have the same issue. You just need to set up the mute correctly, and realise that mute does not necessarily mean what you think it might mean on the iPad
