Adjust Audio Settings in Black Ops 6
Some players say they’ve fixed the Black Ops 6 audio not working by selecting a Default setting for Speakers in the BO6 game. This will configure the game to use your PC’s default sound output device. You can select that setting like this:
- Start the Black Ops 6 game.

- Next, select the Audio tab.
- Choose the Default option on the Speakers/Headphones Game Sound Device drop-down menu.

- In Windows 11, click the More sound settings option. Alternatively, click Sound Control Panel in Windows 10 Settings.
- Right-click your speaker in the Playback tab to select Properties.

The Advanced tab
- Press Apply to set the new sound options.

Check if Black Ops 6 is Muted in the Volume Mixer
Another thing to check is the Black Ops 6 Volume Mixer setting. The Black Ops 6 audio might be muted in the Volume Mixer. This is how you can check and unmute the Black Ops 6 audio via Volume Mixer:
- Run your Black Ops 6 game.
- To access the desktop area, press the Windows logo key.
- Right-click Start to select Settings.
- Click System and Sound.

The Volume mixer settings
- Unmute the sound for Black Ops 6 by clicking the speaker icon in the Volume Mixer settings.
- Also, unmute the sound for Steam if muted.
The above instructions are for Windows 11. Windows 10 users can apply this potential fix by right-clicking the Speakers icon and selecting Open Volume mixer. Then, click the Mute System Sounds button to unmite Black Ops 6.

Update Your PC’s Sound Driver
There’s a possibility an outdated sound driver could be causing Black Ops 6 audio issues. To rememdy that, try updating your PC’s sound driver with Driver Booster.
