They do, just look at the whole of directsoundsink :) The Windows specific
elements need some love in general... and for sound we should also move to
wasapi.

The sleep there basically "implements" a GstClock around the system clock as
apparently used by DirectSound here... in a not so nice way.


The main question here right now is what is wrong with that specific commit?
Why does it cause too short sleeps?
