I start a VoIP call using CallKit, use AVAudioSession.sharedInstance.overrideOutputAudioPort(.speaker) to force the audio to speaker, and then open an AVRoutePickerView.

The selected output in the view is iPhone-- the ear speaker on the iPhone. I would expect it to show instead that speaker is selected.

What could be causing this? Should I be forcing the output to the speaker in a different way? Is there a different way I can expose the route choosing functionality?

What's strange is that if you lock the phone and look at the CallKit UI, it shows that it is routing to speaker

I encountered the same problem. In my code, I overrode the audio route to .none and it worked indeed. But the AvRoutePickerView showed .speaker selected. It confuse me.
