ERR MSS INIT FAILED 150 points to a problem with Microsoft DirectX or the game’s ability to initialize the Multi-Threaded Software Sound (MSS) system. It often appears on launch or when switching graphics settings.
Common causes:
The error code "EXE_ERR_MSS_INIT_FAILED" (often appearing as error 150) indicates a failure to initialize the Miles Sound System. This critical software library handles all audio playback for many Call of Duty titles, most notably Call of Duty 2 and Black Ops 2. Error Summary
Primary Cause: The game is unable to communicate with your sound card or audio software.
Common Triggers: Corrupted game files, outdated audio drivers, or incompatible Windows sound settings. Recommended Solutions 1. Verify and Repair Game Files
The most frequent cause is a missing or damaged .dll file related to audio.
Steam: Right-click the game in your Library > Properties > Installed Files > Verify integrity of game files.
Battle.net: Select the game > click the Gear icon > Scan and Repair. 2. Update or Reinstall Audio Drivers
Outdated drivers can prevent the Miles Sound System from initializing properly.
Open Device Manager and expand Sound, video and game controllers.
Right-click your primary audio device (e.g., Realtek High Definition Audio) and select Update driver.
If the issue persists, visit the Realtek website or your motherboard manufacturer's support page to download the latest official drivers. 3. Adjust Windows Sound Settings
Modern high-fidelity sound settings can sometimes clash with older Call of Duty engines. Go to Control Panel > Sound > Speakers > Properties.
In the Advanced tab, set the default format to 24-bit, 44100 Hz (Studio Quality). Some users found that lowering this to 16-bit 44100 Hz resolves the initialization crash. 4. Run as Administrator
Permissions issues can block the .exe from accessing system audio components. Navigate to your game installation folder.
Right-click the game executable (e.g., cod2.exe or cod2_mp.exe).
Select Properties > Compatibility tab > Check Run this program as an administrator.
