I seem to be having a strange problem with my iPad. The volume only sometimes works. The volume will be fully turned up and not muted, but it won't work. Then, without changing anything, a couple minutes later it will work. Or, I will try to FaceTime someone and I will not hear it ring on my end. Then when they answer, I can't hear them and they can't hear me. I'll try again a second after and it'll work again. It is never consistent though.
Is there anything I can do to fix this?
