static let microphone: AVCaptureDevice.DeviceTypeDiscussion
In iOS and tvOS, the system only exposes one capture device of this type. The audio routing subsystem decides which physical microphone to use, be it a built-in microphone, a wired headset, or an external microphone. The microphone device’s localizedName changes as the audio subsystem switches to a different physical device.
