pa_operation* pa_stream_proplist_update ( pa_stream s,
pa_update_mode_t  mode,
pa_proplist *  p,
pa_stream_success_cb_t  cb,
void *  userdata 
)

Update the property list of the sink input/source output of this stream, adding new entries. Please note that it is highly recommended to set as much properties initially via pa_stream_new_with_proplist() as possible instead a posteriori with this function, since that information may then be used to route this stream to the right device.
