21 * Most thread locking is complete. There may be a few race
22 * conditions still lurking.
23 *
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
