It doesn't happen when .setPreferredInput() is called before unplugging the EarPods. Apps may set a preferred data source by using the setPreferredDataSource:error: method of an AVAudioSessionPortDescription object. The input and routes are optimized for each mode's use case. Returns the value of the property associated with the specified key. Get "current" values once the audio session has been activated. Also, I can subscribe to route change, audio interruption and OS Media Reset/Lost notifications given by the OS - this communication is managed by AVAudioSession - .
