How to Fix Sound on iPad after ios 7 Update

After updating to Apple's latest IOS update 7 for my iPad, I noticed that my alert and notification sounds were very scratchy and annoying.   Just figured out that this can be fixed by going to Settings> Accessibility and making sure that the mono audio is set to OFF under the Hearing section.  

Mine was OFF, but I toggled it On and then OFF again.   Now my alert tones and sounds are back to normal.
