 * Most thread locking is complete. There may be a few race

 *
 * 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
