Create events with |manual_reset| and |initially_signalled| both false
(used to be both true). Delete calls to Set and Reset events from the
{Start,Stop}{Playout,Recording} methods. Then, for each event, there
remains a single call to Set, in the ProcessingAudio loop, and a
single call to Wait, in WaitForPlayoutEnd and WaitForRecordingEnd,
respectively.
