| * |
| * 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 |
