I guess not, but PA does post an event to the application to CORK/UNCORK the
stream, its application responsibility to handle the event and behave
accordingly.
e.g module-cork-music-on-phone , PA posts and event  using
pa_sink_input_send_event(j, PA_STREAM_EVENT_REQUEST_CORK, NULL)
to the application, application need to register for callback using
"pa_stream_set_event_callback" to receive the events from PA.

Sure, you will get enough hints if you go-through the
module-cork-music-on-phone ,so its best to initially modify the existing
module-cork-music-on-phone and base your module on this.
