  28  * TODO:
  29  *      Implement SetCooperativeLevel properly (need to address focus issues)
  30  *      Implement DirectSound3DBuffers (stubs in place)
  31  *      Use hardware 3D support if available
  32  *      Add critical section locking inside Release and AddRef methods
  33  *      Handle static buffers - put those in hardware, non-static not in hardware
  34  *      Hardware DuplicateSoundBuffer
  35  *      Proper volume calculation, and setting volume in HEL primary buffer
  36  *      Optimize WINMM and negotiate fragment size, decrease DS_HEL_MARGIN
