If you use DirectSound-out instead of WAVEout the CPU usage drops.
At least Task Manager shows it that way.

Once Task Manager ( on w2k-SP2 ) showed 50% CPU usage on the graph,
but 2 % in the status bar ( the bottom line in the window ) for several minutes.

So much about its accuracy ...

Do not use top under linux either !
