 // AudioOutputDispatcherImpl is an implementation of AudioOutputDispatcher.
 //
 // To avoid opening and closing audio devices more frequently than necessary,
 // each dispatcher has a pool of inactive physical streams. A stream is closed
 // only if it hasn't been used for a certain period of time (specified via the
 // constructor).
