Recently, my iPod would play no sound even if my headphones weren't plugged in so I would just restart it and it would go back to normal. But today, even if my headphones were plugged in, my iPod would only play sound through the speaker?

- Try cleaning out/blowing out the headphone jack. Try inserting/removing the plug a dozen times or so. There is a little switch in the headphone jack that disconnects the speaker when the headphone jack is inserted.

Try this. If your Side Switch is set to control Lock Rotation, go to Settings > General. Look at Side Switch setting. Turn it to Mute, then check to see that the Side Switch is in the position which allows sound. If not, change Side Switch to play sound. Then immediately, change Side Switch setting back to Lock Rotation. The sound should now play freely. Or perhaps you wish to leave the iPad Side Switch under Mute control.
