Set the callback function that is called whenever the sink/source
* this stream is connected to is suspended or resumed. Use
* pa_stream_is_suspended() to query the new suspend status. Please
* note that the suspend status might also change when the stream is
* moved between devices. Thus if you call this function you very
* likely want to call pa_stream_set_moved_callback() too. This
* notification is only generated when the server is at least
* 0.9.8. \since 0.9.8
