Call of Duty Black Ops: sound not working, sound fix

You suddenly lost sound on Call of Duty Black Ops? In this article we give you simple solutions of this problem.

• The most likely reason for the lack of sound is corrupted game files. To scan them, open the Blizzard Battle.net client and go to Call of Duty: BOCW > Options > Scan and Repair.
• Another reason could be that your output device settings are out of whack. To fix this, press Win+R on your keyboard at the same time. The Run window opens. Type ms-settings:sound > OK. After that, go to the Input section and check if your input device is configured correctly. Check if the checkbox next to Mute microphone in Settings is unchecked and Volume is set to maximum.
• One more reason of the sound issue may be the wrong game settings. In the game, go to Settings > Game Sound and check if the sound is turned on.
• Sometimes after launching the campaign mode of Call Of Duty Black Ops, the sound goes out (just after the cinematic). This doesn't happen in multiplayer mode so you might wonder what the problem is. You need to update the Microsoft DirectX end-user runtime. This link installs a number of runtime libraries from the legacy DirectX SDK for games that use D3DX9, D3DX10, D3DX11, XAudio 2.7, XInput 1.3, XACT and Managed DirectX 1.1.
