/*
|
|
* Note: This file requires multithread ability. It is not possible to
|
|
* implement the stuff in a single thread anyway. And most DirectX apps
|
|
* require threading themselves.
|
|
*
|
|
* Most thread locking is complete. There may be a few race
|
|
* conditions still lurking.
|
|
*
|
|
* Tested with a Soundblaster clone, a Gravis UltraSound Classic,
|
|
* and a Turtle Beach Tropez+.
|
|
*
|
|
* TODO:
|
|
* Implement DirectSoundCapture API
|
|
* Implement SetCooperativeLevel properly (need to address focus issues)
|
|
* Use wavetable synth for static buffers if available
|
|
* Implement DirectSound3DBuffers (stubs in place)
|
|
* Use hardware 3D support if available (OSS support may be needed first)
|
|
* Add support for APIs other than OSS: ALSA (http://alsa.jcu.cz/)
|
|
* and esound (http://www.gnome.org), for instance
|
|
*
|
|
* FIXME: Status needs updating.
|
|
*
|
|
* Status:
|
|
* - Wing Commander 4/W95:
|
|
* The intromovie plays without problems. Nearly lipsynchron.
|
|
* - DiscWorld 2
|
|
* The sound works, but noticeable chunks are left out (from the sound and
|
|
* the animation). Don't know why yet.
|
|
* - Diablo:
|
|
* Sound works, but slows down the movieplayer.
|
|
* - XvT:
|
|
* Doesn't sound yet.
|
|
* - Monkey Island 3:
|
|
* The background sound of the startscreen works ;)
|
|
* - WingCommander Prophecy Demo:
|
|
* Sound works for the intromovie.
|
|
* - Total Annihilation (1998/12/04):
|
|
* Sound plays perfectly in the game, but the Smacker movies
|
|
* (http://www.smacker.com/) play silently.
|
|
* - A-10 Cuba! Demo (1998/12/04):
|
|
* Sound works properly (for some people).
|
|
* - dsstream.exe, from DirectX 5.2 SDK (1998/12/04):
|
|
* Works properly, but requires "-dll -winmm".
|
|
* - dsshow.exe, from DirectX 5.2 SDK (1998/12/04):
|
|
* Initializes the DLL properly with CoCreateInstance(), but the
|
|
* FileOpen dialog box is broken - could not test properly
