Symptoms

On some versions of proton, music will never play in the game.
On any version <=7, music works fine. On any version >7, music will not play. Other sound effects function correctly on all tested versions.
This includes 8, 9, 10, hotfix, experimental, as well as GE for all these versions, CachyOS, and TKG.
Downgrading to proton 7 is not a viable fix because it introduces stability issues, which are absent in modern proton versions. The game runs perfectly on modern proton versions, barring the complete absence of music.

Reproduction

Install the game via Steam, run with any current version of proton. When functioning normally, music should play as soon as the game loads and enters the main menu. However, it does not.
Switch to proton 7 or below and run the game again, the music should now function. You will hear it immediately upon entering the main menu.
