Symptoms

As soon as the game launches the menu music track starts looping even though it's not supposed to be playing, because the intro movie is playing, and when the intro is finished 2 or 3 more music tracks of the same menu music start playing overlapping each other. Also happens in earlier Proton versions.

I have also tried this with upstream Wine, same issue.

Edit: just tested this on Windows 11 and the issue is not present.

Reproduction

Start the game and skip the intro.
