Audio worked on first launch. Once the game crashed for the first time audio no longer worked on the native version. Switching to proton fixes the audio. Audio is still missing when switching back to native .

Game ran about 1h on first launch then crashed, requiring a system reboot to recover. After that the game crashes within 10 minutes of startup every time, completely freezing the PC and requiring a hard reboot. This is true for native and all three windows verions under Proton.
