I have the same problem. If you hard boot your iPad, by pressing the home button and the start button at the same time. After doing this a few times, as many as 10 times, my sound works and I can control it either in settings or via my music player. If you turn off the iPad completely, by sliding the red bar, you will need to perform the hard boot process again after turning on the iPad.
