  * An opened audio device starts out with no audio streams bound. To start
  * audio playing, bind a stream and supply audio data to it. Unlike SDL2,
  * there is no audio callback; you only bind audio streams and make sure they

- * stream may have its own callback, which can be used to simulate SDL2's
