* 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
