Second, my IPad 4th Generation won't make any sound in any apps except for the Internet and my metronome app, which I use for piano practice. So it pretty much doesn't make any sound in my game apps. Any ideas on how to fix it?
You mean sooty123? I dunno, I guess we'll find out in time.
Maybe check your settings? I'm not too sure but aren't you able to turn audio on/off there? If it isn't that maybe another user might know, or look it up on Google. There's probably a help site for stuff like this.
