/*
* Most thread locking is complete. There may be a few race
* conditions still lurking.
*
* Tested with a Soundblaster clone, a Gravis UltraSound Classic,
* and a Turtle Beach Tropez+.
*
* 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, and setting volume in HEL primary buffer
* Optimize WINMM and negotiate fragment size, decrease DS_HEL_MARGIN
