 // AudioInputDeviceManager manages the audio input devices. In particular it
 // communicates with MediaStreamManager and AudioInputRendererHost on the
 // browser IO thread, handles queries like enumerate/open/close from
 // MediaStreamManager and start/stop from AudioInputRendererHost.
 // The work for enumerate/open/close is handled asynchronously on Media Stream
 // device thread, while start/stop are synchronous on the IO thread.
