If you modified your build to use WASAPI, then obviously there is no sync since 
you disabled the code some time ago. Otherwise the sync is the *same* function 
whether using DirectSound or MMDevice. Except for 
IDirectSoundBuffer_GetCurrentPosition() failure or trivially inverted logic, 
the result will be the same.
