Invoking this option switches all output, including voiceover, between your local device and the Bluetooth destination. When connected to a Bluetooth destination, an audio destination rotor option becomes available. Toggling the audio ducking rotor setting allows you to send voiceover output to The connected airplay destination, albeit with significant lag. When connected to an airplay destination, by default, voiceover output remains on the local device. I used an iPad 4th-generation running iOS 10 for this test: Has anyone else tried switching audio destination over AirPlay in IOS 10? Has that option disappeared for you as well? Having this level of audio destination support through AirPlay would still be useful though. I was thinking you'd have the option to switch VoiceOver audio and other audio separately. When switching the audio destination with a headset, both VoiceOver and any other audio (music, movies, etc.) toggle between the IOS device speaker and Bluetooth headset. Interestingly, it doesn't work how I'd expect. When connected to a Bluetooth headset however, the option appears. Audio Destination didn't appear with Audio Ducking on or off. Apple suggested experimenting with Audio Ducking to see if that would make any difference, but it didn't. I tried this same process in IOS 10, and the option has disappeared when using AirPlay to Reflector. It was very helpful having the audio destination option in IOS 9. In IOS 9, VoiceOver added a feature, when connected to an AirPlay device, that would add an Audio Destination option to your rotor automatically when connected, but wouldn't be when not in AirPlay. Reflector turns your computer into an AirPlay server, which is great for doing presentations and recording videos. In IOS 9, I would connect my iPhone and iPad to an AirPlay server, occasionally Apple TV, but more often, the Reflector 2 PC app:

So I have done some more experimenting, and here's what I found. I originally contacted Apple Accessibility about this problem, and they gave me a couple of ideas to try.
