Your mic is muted, disabled in settings, or the game hasn't detected it yet

When your open mic stops working in Call of Duty Black Ops 6, the problem is almost always one of three things: the mic itself is muted somewhere in your system, the game's audio settings have voice chat turned off, or your console or PC hasn't recognized the microphone as an input device. The fastest way to fix it is to check these three places in order, starting with what you can see right now.

Open mic means your voice transmits to other players automatically without pressing a button — you don't have to hold down a key or trigger to talk. If it stops working mid-game or never worked at all, you're usually looking at a mute toggle you didn't realize was on, not a hardware failure.

Key Takeaways

  • Check your microphone's physical mute button first — many headsets have a switch or button on the cable or ear cup that silences the mic without any other sign it's off.
  • In Black Ops 6, go to Settings, Audio, and confirm Voice Chat is set to On and your microphone input device is selected, not set to None.
  • On console, restart your system entirely if the mic still doesn't show up in the device list — this forces the system to re-detect connected hardware.
  • If you're on PC, check Windows Sound Settings to confirm your mic is set as the default recording device and is not disabled.
  • Test your mic in a party or private match before jumping into multiplayer, so you know whether the problem is the game or your setup.

Check the physical mute button on your headset

Most gaming headsets have a mute switch or button on the microphone boom itself, on the cable, or on the ear cup. Look for a small switch or button labeled with a microphone icon with a line through it. If it's in the muted position, your mic won't transmit even if everything else is set correctly.

Some headsets also have a volume dial on the mic boom — turning it all the way down can mute the microphone. Check both the switch and any dials or buttons on the headset itself. This is the single most common reason open mic stops working, because the mute toggle is straightforward to bump without noticing.

Turn on Voice Chat in Black Ops 6 settings

Open Black Ops 6 and go to Settings. Select Audio, then look for Voice Chat. Make sure it is set to On, not Off or Disabled. While you're there, check the Microphone Input Device setting — it should show the name of your headset or microphone, not None or Disabled.

If the Microphone Input Device shows None, click on it and select your headset from the list. If your headset doesn't appear in the list at all, your system hasn't detected it yet — skip to the console or PC section below. If Voice Chat is already on and your mic is selected, move to the next step.

Restart your console or PC to force hardware detection

On PlayStation 5 or Xbox Series X|S, hold the power button until the console shuts down completely — don't just put it in rest mode. Wait 30 seconds, then turn it back on. This forces the system to re-scan all connected devices, including your microphone. Once it boots, plug your headset back in if you unplugged it, then launch Black Ops 6 and check the Audio settings again.

On PC, restart Windows entirely. If you're using a USB headset, unplug it, restart, then plug it back in after Windows finishes booting. This gives Windows time to install or refresh the driver for your microphone. Then open Black Ops 6 and check whether your mic now appears in the Microphone Input Device list.

Check your Windows or console audio settings

On Windows 10 or 11, right-click the speaker icon in the system tray and select Open Sound Settings. Scroll down to Advanced and click App Volume and Device Preferences. Find Call of Duty Black Ops 6 in the list. Make sure the microphone device next to it is set to your headset, not None or a different device.

If your headset doesn't appear as an option, go back to the main Sound Settings page and look for Recording Devices. Right-click your microphone and make sure it is not set to Disabled. If it shows as disabled, click Enable. Then return to Black Ops 6 and check the Audio settings again.

On PlayStation 5, go to Settings, Sound, and select Microphone. Make sure it is set to On and the correct USB device or headset is selected. On Xbox Series X|S, go to Settings, General, Volume and Audio Output, then Device and Accessories. Select your headset and confirm the microphone is enabled.

Test your mic in a private match or party

Before jumping into multiplayer, test your open mic in a private match or a party chat with a friend. This tells you whether the problem is your setup or something specific to the multiplayer server. Start a private match against bots, enable open mic, and speak — you should hear your own voice in the headset if the mic is working.

If you hear yourself, your mic is working and the problem may be a server issue or a mute setting specific to multiplayer. If you don't hear yourself, go back through the steps above. If your friend in a party can hear you but multiplayer players cannot, the issue is likely a game setting or server-side mute, not your hardware.

Update your headset drivers or firmware

Some gaming headsets require driver software or firmware updates to work properly with newer games. Check the manufacturer's website — search for your headset model and look for a support or downloads page. read any available driver updates and install them, then restart your system.

If your headset came with a companion app (like SteelSeries GG, HyperX NGenuity, or Corsair iCUE), open it and check for firmware updates. Install any updates and restart. Then launch Black Ops 6 and test your mic again. Outdated drivers are less common than mute toggles or settings, but they do cause problems after major game updates.

Frequently Asked Questions

Why can my friends hear me in party chat but not in the game?

The game's Voice Chat setting is off or your mic is muted in Black Ops 6 specifically. Go to Settings, Audio, and confirm Voice Chat is On and your microphone device is selected. Party chat uses a different audio path than in-game voice, so one can work while the other doesn't.

My mic shows up in settings but still doesn't work in Black Ops 6

Restart the game entirely — don't just return to the menu. Close Black Ops 6 completely, wait 10 seconds, and relaunch it. Sometimes the game doesn't detect the mic until it initializes after a fresh start. If that doesn't work, restart your console or PC.

Can I use a USB headset instead of a wireless one?

Yes, USB headsets work fine in Black Ops 6 on both console and PC. Just plug it in, let your system detect it, then select it in the game's Microphone Input Device setting. USB headsets are often easier to troubleshoot because they don't require pairing or driver installation.

What if my microphone is disabled in Windows but I can't enable it?

Right-click the disabled microphone in Sound Settings, Recording Devices, and select Enable. If that option doesn't appear, the device may be unplugged or disconnected. Check the USB cable or wireless receiver. If it's plugged in and still won't enable, try a different USB port on your PC.

Do I need to buy a new headset if none of these steps work?

Not necessarily. If your mic works in Windows Sound Settings or console audio settings but not in Black Ops 6, the problem is the game, not your hardware. Try launching a different game that uses voice chat to confirm your mic works elsewhere. If it does, contact Activision support — the issue may be account-specific or server-side.
