Raw Blame History

/* DirectSound
*
* Copyright 1998 Marcus Meissner
*/
/*
* 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.
*
* FIXME: This file is full of race conditions and unlocked variable access
* from two threads. But we usually don't need to bother.
*
* Tested with a Soundblaster clone and a Gravis UltraSound Classic.
*
* 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.
