Thanks for the quick input Halle.
That’s a very good idea, to stop worrying about the headphone route changes and focus only on simple StopListening() calls.
You’re right that all StopListening() calls fail, this will make testing easier and the logs smaller.

I have modified my app to start OpenEars and after it’s fully initialized it waits 3 seconds and then calls StopListening().
I play no audio at all in this test.

Here’s the full log:

The I/O stop error still shows up.
I still don’t have more details on the Unity audio behavior other than the audio session settings dumps, however.
Could you give me some pointers on what kind of audio information I should be adding to the logs so I can look further? The AVAudioSession settings are not enough I suppose?
