Its a bug in the ipad/iphone, either restart the phone/itouch/ipad, or kill off all the audio apps (double tap, then hold the app icon you want to kill, hit the -)

On ipad sometimes double tapping and scrolling over you will see the airplay icon and not necessarily in the app itself.

I run across this all the time even with appletvs' the denons set to dynamic or static ip? more than one on the network?
