I would like to know how the audio destination setting works in iOS 9.2.3 I am trying to switch my audio destination between my made for iPhone hearing aids and the phone's speakers. The setting appears at random on the rotor and I cannot figure out the pattern. And to compound the problem, it is not even a setting to check in the Voiceover rotor settings. I wish it was available at all times.
Any idea how the iOS decides its appearance?
