Symptoms

Playing the game is OK, but seems to suffer from serious issue with sound. When running the game from Steam (which requires no additional setup at all), it works, but the frame rate suffers and all the sounds are echoing/cracking.

I have also tried running the game with a different version of WINE via Lutris (I just pointed Lutris at the executable delivered by Steam), which does not have this problem. It also has a better framerate and smoother gameplay.

So this has to have something to do with something that's on or off in "lutris-fshack-5.6-2-x86_64"

Reproduction

1. Install game from Steam
2. Run it using Proton 5.0 (or any version or Proton-GE)
3. Notice awful sound and impacted framerate
4. Install Lutris
5. Configure a new game using lutris-fshack-5.6-2-x86_64 as the runner and run the game
6. Notice smooth framerates and good sound
7. ???
8. Profit!
