I know you say not to use a throttle, but for some reason it absolutely does not work without one. Any idea why that would be? It sounds very distorted and sped up, and then I get a bunch of xO errors. With throttling it works perfectly.
The instantiation of an audio_sink is typically:
audio_sink (int sample_rate,
const std::string device_name,
and by default "do_block" is supposed to be true ... but for some reason either it's false in your case (instantiated that way?), or maybe something is broken in the OSX audio sink.
In your Python script, try instantiating the audio_sink with the sample rate, the device name (I think OSX uses numbers, e.g., "1", "2", etc.), and true for blocking. If that doesn't work, then something is broken somewhere. - MLD
