// Drives streaming-source refills once per event pump.
//
// Audio::pump has nothing to do with platform events, but it does need a
// per-frame tick and the event pump was the only one available -- so the event
// module called into audio. Hanging it off the sink's end-of-pump hook keeps
// the timing identical without the dependency.
