i checked the control center (swipe up on bottom of screen), the mute switch, all my setting the sound is all the way up. I fell asleep last night watching netflix with the sound only on 1 bar out of 16, ipad automatically turns off after 5 mins of not touching so after the movie was over it went into lock mode right away, then when i came back from school the next day and unlocked my ipad to listen to music, there was no sound. Please help, just bought this thing 2 months ago and i dont want it to be done for already
