IDirectSound implementation.
Added proper COM behavior for QueryInterface for IDirectSound and
IDirectSound8.
Fixed a bug in the dsound.h header file for IDirectSound8
CreateSoundBuffer and DuplicateSoundBuffer.
Added new tests for proper COM behavior and enables some commented out
code for tests that work on windows. Added new tests for
IDirectSound8.
3D sound now plays in 3D.
COM interfaces should be correct for buffers and 3D stuff. The COM
interface is broken on notifications but I will fix that next.
Fixed the bug when closing and opening the same or another sound
device quickly.
Fixed some locking but there is a lot of work left yet.
level just like the direct sound control panel app.
More work on the full duplex interface so the compile warning is no
longer generated. Full duplex interface is still stubbed out.
Moved full duplex mixer reset fix into wineoss driver where it
belongs.
Added some more locking fixes.
Capture and full duplex are now stable.
separate files. Split primary buffer and secondary buffer interfaces
into separate implementations. Made the primary buffer state part of
the dsound object, so primary buffer objects can be created and
refcounted independently. Made the interfaces follow COM aggregation
rules more closely. Converted the dsound critical section to a R/W
lock to improve potential remixing concurrency. Fixed various bugs and
refcounting issues.
