* Most thread locking is complete. There may be a few race
* conditions still lurking.
*
* TODO:
* Implement SetCooperativeLevel properly (need to address focus issues)
* Implement DirectSound3DBuffers (stubs in place)
* Use hardware 3D support if available
* Add critical section locking inside Release and AddRef methods
* Handle static buffers - put those in hardware, non-static not in hardware
* Hardware DuplicateSoundBuffer
* Proper volume calculation for 3d buffers
* Remove DS_HEL_FRAGS and use mixer fragment length for it
