  24  * TODO:
  25  *      Implement SetCooperativeLevel properly (need to address focus issues)
  26  *      Implement DirectSound3DBuffers (stubs in place)
  27  *      Use hardware 3D support if available
  28  *      Add critical section locking inside Release and AddRef methods
  29  *      Handle static buffers - put those in hardware, non-static not in hardware
  30  *      Hardware DuplicateSoundBuffer
  31  *      Proper volume calculation for 3d buffers
  32  *      Remove DS_HEL_FRAGS and use mixer fragment length for it
