    """Plays the given sound.

    @input Play: Plays the sound, or if paused, resumes the playback.
        The exact behaviour depends on the Retrigger option (see below).
    @input Pause: Pauses the playing sound. If no sound is playing,
        nothing happens.
    @input Stop: Stops the playing sound. If the playback is paused,
        this will reset the playback position to the start of the sound.
    @input Update Volume: Updates the volume of the current playback.
    @input Volume: Volume of the playback. Typically ranges from 0 to 1.

    @output Out: activated once when Play is activated.
    @output Running: activated while the playback is active.
    @output Done: activated when the playback has finished or was
        stopped manually.

    @option Sound/Sound Name: specify a sound by a resource or a string name
    @option Sound: The sound that will be played.
    @option Stream: Stream the sound from disk.
    @option Loop: Whether to loop the playback.
    @option Retrigger: If true, the playback position will be reset to
        the beginning on each activation of Play. If false, the playback
        will continue at the current position.
    @option Sample Rate: Manually override the sample rate of the sound
        (this controls the pitch and the playback speed).
