Mic Not Working on Windows 11: Fixes

When nobody can hear you on a call, the cause is usually a setting, not a broken microphone. Work through these fixes in order and check the result after each one with our mic test with playback.

By Ritvik Kudalkar, published . A 7 minute read.

Test as you go

Open the mic test in a new tab and re-check after each fix.

Open Mic Test

1. Check the Hardware Mute and Connection

Look for a mute switch on the headset cable, a mute button on the earcup, or a flip-up boom that mutes when raised. Unplug the mic and plug it back in firmly. For USB mics, try a different port on the computer itself rather than a hub or monitor. For 3.5 mm headsets with a single plug, a desktop PC with separate pink and green jacks needs a splitter, or Windows will not see the mic at all.

2. Turn On Microphone Privacy Access

Windows 11 can block every app from using the mic. Open Settings > Privacy & security > Microphone and turn on:

  • Microphone access (the main switch)
  • Let apps access your microphone, plus the switch for each app you use
  • Let desktop apps access your microphone, which covers Chrome, Edge, Discord, Zoom and most games

This is the most common fix, especially after a Windows update.

3. Choose the Right Input Device

Open Settings > System > Sound and look under Input. Select the microphone you want to use. Speak and watch the volume bar under it. If it moves here but not in your app, the app is set to a different device, so check its own audio settings.

Laptops often have a built-in array mic as well as your headset, and webcams add another one. It is easy for Windows or an app to pick the wrong one.

4. Raise the Input Volume

In Settings > System > Sound, select your microphone and drag Input volume to 75–100. Some mics also have a separate boost control: open More sound settings, go to the Recording tab, open the mic's Properties and look under Levels for Microphone Boost. Add boost in small steps, because too much adds hiss.

Use the level meter in our mic test to find the right level: green when you speak normally, touching yellow when you speak loudly, and never red.

5. Make Sure the Mic Isn't Disabled

In More sound settings > Recording, right-click an empty area and tick Show Disabled Devices. If your mic appears greyed out, right-click it and choose Enable, then Set as Default Device.

6. Turn Off Exclusive Mode

Exclusive mode lets one app take full control of the mic, which can block every other app. Open the mic's Properties from the Recording tab, go to Advanced, and untick both Allow applications to take exclusive control boxes. Restart the apps you use.

7. Update or Reinstall the Audio Driver

  1. Right-click Start and open Device Manager.
  2. Expand Audio inputs and outputs, right-click your microphone and choose Uninstall device.
  3. Restart the PC. Windows reinstalls the driver automatically.
  4. If that doesn't help, install the latest audio driver from your laptop or motherboard maker (often Realtek), or the headset maker's software.

8. Run the Recording Audio Troubleshooter

Open Settings > System > Troubleshoot > Other troubleshooters and run Recording Audio, or use Get Help. It resets services and catches settings that are easy to miss.

9. Rule Out a Hardware Fault

Plug the microphone into another computer or phone and open the mic test there. If it fails on every device, the mic, its cable or its plug is faulty. If it works elsewhere, the problem is your PC's port or software.

Frequently Asked Questions

Why did my mic stop working after a Windows update?

Feature updates sometimes reset microphone privacy settings, switch the default input device, or replace your audio driver with a generic Microsoft one. Check Settings > Privacy & security > Microphone first, then the default input in Settings > System > Sound, then reinstall the driver from your PC or headset maker.

My mic works in one app but not another. Why?

Each app can choose its own input device, and Windows lets you block microphone access per app. Check the input device inside the app's own settings, make sure the app is allowed under Microphone privacy settings, and turn off exclusive mode so one app cannot lock the mic for itself.

How do I know if my microphone is broken?

Test it on a second device. If it fails on a phone or another computer too, the mic, cable or headset is faulty. If it works elsewhere, the problem is in Windows settings, drivers or the port on your PC.

Why does my mic sound robotic or choppy?

Audio enhancements, a weak Bluetooth connection or an overloaded USB hub are the usual causes. Turn off audio enhancements in the mic's properties, connect USB headsets directly to the PC, and avoid using the headset's Hands-Free Bluetooth mode for music and calls at the same time.

Why is my Bluetooth headset mic so poor quality?

Most Bluetooth headsets switch to the Hands-Free (HFP) profile when the mic is in use, which limits audio to narrowband quality. This is a Bluetooth limitation rather than a fault. Headsets with their own USB dongle avoid it.
