   7  * Note: This file requires multithread ability. It is not possible to
   8  * implement the stuff in a single thread anyway. And most DirectX apps
   9  * require threading themselves.
  10  *
  11  * Most thread locking is complete. There may be a few race
  12  * conditions still lurking.
  13  *
  14  * Tested with a Soundblaster clone, a Gravis UltraSound Classic,
  15  * and a Turtle Beach Tropez+.
  16  *
  17  * TODO:
  18  *      Implement DirectSoundCapture API
  19  *      Implement SetCooperativeLevel properly (need to address focus issues)
  20  *      Use wavetable synth for static buffers if available
  21  *      Implement DirectSound3DBuffers (stubs in place)
  22  *      Use hardware 3D support if available (OSS support may be needed first)
  23  *      Add support for APIs other than OSS: ALSA (http://alsa.jcu.cz/)
  24  *      and esound (http://www.gnome.org), for instance
  25  *
  26  * FIXME: Status needs updating.
  27  *
  28  * Status:
  29  * - Wing Commander 4/W95:
  30  *   The intromovie plays without problems. Nearly lipsynchron.
  31  * - DiscWorld 2
  32  *   The sound works, but noticeable chunks are left out (from the sound and
  33  *   the animation). Don't know why yet.
  34  * - Diablo:
  35  *   Sound works, but slows down the movieplayer.
  36  * - XvT:
  37  *   Doesn't sound yet.
  38  * - Monkey Island 3:
  39  *   The background sound of the startscreen works ;)
  40  * - WingCommander Prophecy Demo:
  41  *   Sound works for the intromovie.
  42  * - Total Annihilation (1998/12/04):
  43  *   Sound plays perfectly in the game, but the Smacker movies
  44  *   (http://www.smacker.com/) play silently.
  45  * - A-10 Cuba! Demo (1998/12/04):
  46  *   Sound works properly (for some people).
  47  * - dsstream.exe, from DirectX 5.2 SDK (1998/12/04):
  48  *   Works properly, but requires "-dll -winmm".
  49  * - dsshow.exe, from DirectX 5.2 SDK (1998/12/04):
  50  *   Initializes the DLL properly with CoCreateInstance(), but the
  51  *   FileOpen dialog box is broken - could not test properly
  52  * - The Dilbert Desktop Game: works (SB16)
