Further to my previous post: It's even worse! When you double click the home button while the app is in the foreground, then scroll left to the sound control panel, and then tap the play button, and tap the pause button to stop the sound, your app will continue to show receive sound but not play any. Then when you push the off button on top of the iPhone, the wifi connection will stay on without the user knowing (when you turn the iPhone on again it will show the screen of your app still streaming, but no sound is playing).

This will drain the battery!
