Yes, it works as expected and fixes the issue. I realize that it can
potentially have some caveats. During the brief testing with the demo I could
not hear obvious sound problems.

FWIW, I found what MS says about 10ms quantum [1]:
"All audio processing takes place in a separate thread with a periodicity
defined by the graph's quantum (currently 10 milliseconds on Microsoft Windows,
and 5 1/3 milliseconds on Xbox 360). Every quantum milliseconds, the thread
wakes up and disperses quantum milliseconds of audio data through the entire
graph."
