10: in wasapisink this will be used automatically if available; in
wasapisrc it will have to be enabled explicitly via the
"use-audioclient3" property, as capturing audio with low latency and
without glitches seems to require setting the realtime priority of
the entire pipeline to "critical", which cannot be done from inside
the element, but has to be done in the application.
