• [x] that I haven't found an existing compatibility report for this game.
• [x] that I have checked whether there are updates for my system available.

Symptoms

Some audio completely cuts out (music and dialogue) after ~5–10 minutes of gameplay or immediately after triggering a fast travel loading screen. The ambient SFX keep working all the time.

• Rendering: The 3D graphics pipeline continues running smoothly after the audio loss.

• VRAM Behavior: Monitored via Mission Center / MangoHud. VRAM usage remains completely stable at ~6.0 – 7.3 GB out of 12 GB. This is not a VRAM saturation issue.

• Crash Trigger: Opening the pause menu or inventory after the audio stream dies causes an instant crash to desktop (deadlock on the XAudio2 thread).

• Failed Workarounds: Lowering textures to Medium, capping frame rate (45/60 FPS), forcing WINEDLLOVERRIDES="xaudio2_9=n,b", modifying system file descriptor limits (ulimit), switching display modes (Fullscreen/Borderless), and testing multiple Proton versions (8.0, Experimental, Bleeding-Edge, Hotfix).

Reproduction

1. Launch Horizon Forbidden West on a Bazzite system with an NVIDIA RTX GPU.
2. Play normally for 5–10 minutes or trigger fast travel between campfires 2–3 times.
3. Observe all audio output stopping completely while rendering continues.
4. Press ESC / Start button to open the menu — the game immediately crashes to desktop.
