I searched the threads and didn't see this issue anywhere. I have the Doodle Jump game app on my 4s. The audio component of the game will randomly stop working and when it does I also lose the audio on my text notifications, but the phone ringer continues to work. The only way to get the audio to resume on the game and for text notifications is to shut the phone off and turn it back on. Am I missing something here or is this an odd issue? Any help will be appreciated!
