SetNotificationFreq is definitely the trick here (I remember a very
confusing week trying to figure out this very problem). There should be
a note in the WaveCyclic docs mentioning the link to AllocatorFraming;
this would clear up a lot of confusion.
However, I can't see how changing a pass-by-value parameter (Interval)
could make a difference, except in your own code. Returning the correct
interval as the return value and setting *FramingSize works fine for me...

PS - Is it just me, or does 1ms granularity seem a bit chunky for the
notification interval? :)
