Hi,

so I get the problem on Wine and Windows that the audio appears to be muffled. If I record the audio in Audacity the frequencies above 11 kHz are cut off. So I guess the DirectSound whatever is only running at 22 kHz samplerate.
Is there any way to fix this? I know there are plenty of ddraw wrappers, but I wasn't able to find any for dsound.

This is especially noticable on the music which sounds a lot clearer when playing back through a regular player.

Hello,

Excuse the late reply. I am running S4 on XUbuntu (19.04) under wine and I did not notice any difference in sound whatsoever.

I can check with audacity to verify this.

EDIT: I, too, can verify your observation about the samplerate.
Not having heard the music through a regular player, I must say that between playing the game on XP and Ubuntu I can not hear any difference. Are you certain the issue lies within Wine and is not caused by AIL setting the samplerate to 11kHz?

Some time has passen now and I found out the reason. When SoundEngine.dll is initialized, it is so with a parameter of "22050" which causes the muffled audio.

To change that, open S4_main.exe in a hexeditor and search for bytes "22 56 00 00" (22050 in decimal). I only have one occurance of this sequence. Change that sequence to "44 AC 00 00" (44100 in decimal). That should fix the problem, allthough I have not extensively tested this yet.
