3. Check the Game’s Installation Path Black Ops II has issues with non-standard characters or very long paths.

4. Run the Game in Windows 7 Compatibility Mode

5. Set System Locale to English (US) If your Windows display language isn’t English, the game may look for the wrong sound bank.

6. Manually Replace the Sound Bank (Last Resort) If verification doesn’t work, the cmn-root.english file may be missing from: ...\Call of Duty Black Ops II\sound\

    The "sound bank failed to load cmn-root.english" error in Call of Duty: Black Ops II
