Francois Gouget 32140adefa DSB.SetFormat:Trace the requested format as soon as possible in case
it is not supported and simplify validity check.
Initialize the buffer format, and only from the fields we checked.
DirectSoundCreate8 fully initializes the buffer format (just in case).

/*
* 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
