I have not (yet) implemented the ok_to_block parameter in audio_windows
So remove the last parameter (False) in the instantiation of the audio sink.
So change:
        audio_sink = audio.sink (int (audio_rate),
                                 options.audio_output,
                                 False)  # ok_to_block

Into:
        audio_sink = audio.sink (int (audio_rate),
                                 options.audio_output)
And it should work.
