            Bug ID: 44783
           Summary: Jedi Knight Dark Forces II/Mysteries of the Sith,
                    choppy audio causing very poor performance
           Product: Wine
           Version: 3.4
          Hardware: x86-64
                OS: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: -unknown
          Assignee: wine-bugs at winehq.org
          Reporter: libsanorec at hotmail.com
      Distribution: ---

After a somewhat recent upgrade in Wine (don't remember from what version
though, but it was a very old one), I've been having problems with audio in
both JK and MotS, where sounds playing in-game will lower fps significantly and
sound very choppy.

In Jedi Knight, causing sounds to play continuously (say, by firing a very fast
gun right into a wall) will cause the framerate to drop drastically, from the
usual already very low average of 30fps to around 10fps. Needless to say, the
sound will become increasingly choppy the lower the framerate is. The problem
is less present but still there when playing the game without 3d Acceleration,
and the average FPS is a lot higher as well.

I normally use JACK audio with a Pulse Audio module, but having JACK on or off
doesn't seem to make any difference in game performance. Changing the Wine
audio driver to winealsa or winepulse also didn't have any noticeable
difference. I however did not experience any such performance drops when
running the game with Wine audio disabled.

Running from console won't cause any error or "fixme" messages to print when
choppiness happens.

In MotS the problem is even worse: audio choppiness happens in almost every
frame, leading to short freezes and overall complete unplayability. I believe
this might have something to do with the sample rate for the sounds in these
games: JK uses 22050Hz and MotS uses 11025Hz.


After resetting the ".wine" directory, overall performance seems much better
(still around 30fps, but far more stable), but the audio is still very choppy.
