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 */ #include "config.h" #include #include #include #include #include #include #include #include #include /* Insomnia - pow() function */ #include "dsound.h" #include "winuser.h" #include "winerror.h" #include "multimedia.h" #include "wine/obj_base.h" #include "thread.h" #include "debug.h" DEFAULT_DEBUG_CHANNEL(dsound) /***************************************************************************** * Predeclare the interface implementation structures */ typedef struct IDirectSoundImpl IDirectSoundImpl;
