I'd like to extract the sound files from this old game from SSI : Chaos Gate,which seem to be stored in what seems to be an archive named wh40.ds in the Sounds folder. I'm 100% sure it contains *.wav files because :
-In the game's *.dat files, there are mention of *.wav files
-When I open the file with a hex editor, I can see plenty of files named xxxx.wav
So far I've been unable to extract any of them with many of the rippers/extractors I've tried

I hope you guys can help me !
Here is a link of the demo of this game :
