2. Check Language & Region Settings

• Ensure Windows system language matches the game’s language (English).
• In Steam: BO2 Properties → Language → Set to English.
• Delete or rename localization.txt in the game root if present (forces re-detect).

3. Missing Windows Redistributables

The game relies on legacy DirectX and Visual C++ libraries. If these are missing or outdated, the audio engine fails to initialize.

2. Navigate to the Call of Duty: Black Ops 2 game page.
3. Click on "Options" (or "Settings" on console) and select "Scan and Repair" (or "Check for Updates" on console).
4. Allow the scan to complete. If any corrupted files are found, they will be repaired or updated.
