No sound coming from my iPhone 4s.
I just recently got an iPhone 4s. I am getting no sounds coming from it though. The ringer works, but all other sound is off unless the headphones are plugged in. This goes for recorded movies, music I purchased, youtube videos, the sound effects when I slide the login button. Everything is silent. I have restarted it a few times now, but to no avail. Even the sound buttons on the side do nothing; now they don't even bring up the sound volume overlay.
Any idea what might be wrong?
Thanks!
iPhone 4S, iOS 5.0.1
