Welcome,
This isn’t possible with the current version of OpenEars, although I am working on it for the upcoming version 2.0 (I don’t know when it will ship).
The issue is that AVCaptureSession requires a completely different audio session from OpenEars and vice versa, so they currently cannot each allow the other access to the singular audio stream successfully.
This is expected behavior since there are no examples of iOS audio objects in which two instantiated objects can make simultaneous use of a singular audio stream, but nonetheless I’m working on trying to make this possible with OpenEars and AVCaptureSession.
