The game needs an external library for audio to work, which it doesn't include by default, leading to missing audio in-game, which apparently also affects Windows players. This library used to be included in Wine, which allowed the audio to work, but it was removed in Wine 8 due to this library being deprecated, breaking audio in Proton 8 and later, and Valve has no plans to fix this. It is fortunately still able to be downloaded using Protontricks.
