All data is handled through callbacks. All we need to do is iterate over the main loop and let

The write callback is fired from pa_mainloop_iterate(). This meets miniaudio's specification that
the data callback be fired from the step() function, so there's no need to do anything here except
iterate the PulseAudio loop.
