Okay. Therefore the pulse plugin has to call pa_stream_drain() from its IO plug pointer callback in case of state DRAINING, right? > But still it's outside the plugin, drain callback isn't called there. I think this is not the best design decision because there is an IO plug callback for each state transitions. Only for transitions to draining in nonblocking mode there will be no IO plug callback. I think this could be confusing for some IO plugin developers. What do you think?
