- * 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
