losing sound in most app on the ipad 4
I have both an iPad 4 and an iPad Air with similar apps on both. I have notice recently that most of the apps on the iPad 4 are having problems with the volume control. I have turned up the volume using the volume control buttons on the side, the volume control selector button in "Settings" under the "Sounds" option, and finally I have tried increasing the volume inside each app to no avail. All of the apps are working perfectly with the exception that I am having trouble trying to get any sound coming from them. With the iPad Air I am using the same apps and haven't encounter any problems with sound. Is there anyone else out there that seem to be having a similar problem? Interestingly I can play my music and videos and even apps such as "ClockXtmlHD" seems to be working just fine but the other games are the ones having the problem. A little help anyone?
iPad 2, iOS 4.3.3
