 // Creates an audio output stream based on the PulseAudio asynchronous API.
 //
 // If the stream is successfully opened, Close() must be called before the
 // stream is deleted as Close() is responsible for ensuring resource cleanup
 // occurs.
 //
 // This object is designed so that all AudioOutputStream methods will be called
 // on the same thread that created the object.
 //
 // WARNING: This object blocks on internal PulseAudio calls in Open() while
 // waiting for PulseAudio's context structure to be ready.  It also blocks in
 // inside PulseAudio in Start() and repeated during playback, waiting for
 // PulseAudio write callbacks to occur.
