Symptoms

Can't hear any music or sounds while playing the game. Tried enabling dsound or changing the sound parameters in winecfg so I wouldn't use the "default" ones (seems to be a problem with gamemaker games) but with no success.

Reproduction

Just launch the game and play.

Seems it's a MIDI problem : "No software synthesizer midi port found, Midi sound output probably won't work wine" , error I got when I launched the game with Wine and the terminal. This error seems to have disappeared after installing Timidity (but not sure)

Tried this tutorial and install Timidity but it doesn't detect the game : https://manerosss.wordpress.com/2017/06/22/wine-midi-linux/comment-page-1/

If someone has an easy way to fix that MIDI problem it would be awesome.

I managed to make the sound work on Playonlinux, you need to install "directmusic" and "dsound" to do so. However I didn't manage to install it with Protontricks / Winetricks and always get this error:

At last I managed to make the sound work on Proton, use winetricks to install directmusic before launching the game for the first time. If you already did it, delete the game's folder in compatdata and launch "winetricks directmusic", then launch the game.

@nicoco59 I'm not sure how you managed to use winetricks to install anything before starting the game at least one time, since the games wineprefix doesn't exist prior to starting the game.

But I managed to get the sound working myself using protontricks.
After starting the game at least once, run the following in a bash terminal:

/usr/bin/ls ~/.local/share/Steam/steamapps/compatdata/947600/pfx/dosdevices/c:/windows/syswow64/{dsound,dmband,dmcompos,dmime,dmloader,dmscript,dmstyle,dmsynth,dmusic,dswave}*.dll | while read file; do test -L "$file" && mv "$file" "$file".bak; done
protontricks 947600 -q dsound directmusic

In short, all dll-files that we want to install with protontricks already exists. These dll-files have been installed by Steam. But for some reason they are not able to make the sound work in this game.

So by renaming these dll-files protontricks can install dsound and directmusic, and sound now works in the game.

Works on Proton 8.0-5 and above without noticeable issues, no winetricks/protontricks needed.
