Windows 11 Microphone Not Working: Privacy and Driver Fixes

If you are dealing with a Windows 11 microphone not working, the cause is usually one of four things: the mic is muted or badly connected, Windows privacy settings block apps from using it, the wrong input device is selected, or the audio driver has a problem. Less often the microphone itself is faulty. This guide checks each in that order on Windows 11 version 24H2 and 25H2, Home and Pro, and the same steps apply to built-in laptop mics, USB microphones, headsets and webcams with a microphone.

If you cannot hear anything either, start with the Windows 11 audio not working guide, because both problems often share a driver.

Quick hardware checks

1. Mute switches. Many headsets have a mute button on the earcup or a slider on the cable, and some light up red when muted. Some gaming headsets mute when the boom mic is flipped up.
2. The right jack. On a desktop, the pink 3.5 mm socket is the microphone input. A headset with a single combined plug needs a combined headset jack or a splitter; plugged into a plain headphone socket, its mic is not connected.
3. USB and docks. Plug a USB mic or headset straight into the PC rather than through a hub or monitor, and try another port.
4. Bluetooth. Make sure the headset is paired and connected in Settings > Bluetooth & devices. When the mic is in use, many Bluetooth headsets switch to a lower-quality hands-free mode; that is expected. If pairing itself is the problem, see Windows 11 Bluetooth not working.
5. Restart. A restart releases a microphone that a crashed app may still be holding.

Allow microphone access in privacy settings

Windows 11 has three switches that can silently block a microphone. All three are on the same page:

1. Go to Settings > Privacy & security > Microphone.
2. Turn on Microphone access. If it is off, no app can use any microphone.
3. Turn on Let apps access your microphone, then check that the app you need is switched on in the list. This list shows apps from Microsoft Store.
4. Turn on Let desktop apps access your microphone. Desktop apps such as Zoom, Discord and most games depend on this setting and cannot be controlled one by one.
5. If your mic is built into a webcam, also check Settings > Privacy & security > Camera.

A microphone icon appears in the taskbar’s notification area when an app is using the mic, which is a quick way to confirm access works. If a switch is greyed out, an administrator or work policy controls it. Our privacy settings guide covers the other app permissions on that page.

Choose, enable and test the input device

1. Go to Settings > System > Sound.
2. Under Input, open Choose a device for speaking or recording and select your microphone.
3. Select the arrow next to the device to open its properties.
4. Under Audio, make sure the device is allowed. If you see Allow, select it; Don’t allow disables the device for apps and Windows.
5. Set Input volume. A slider at or near zero makes the mic appear dead.
6. Select Start test, speak normally, then Stop test. Play the recorded sample to hear yourself.

If the device is missing from the Input list, scroll down to Advanced > All sound devices. Disabled inputs appear there and can be allowed again. Some properties pages also have an Audio enhancements option; if your voice sounds robotic or cuts out, try turning enhancements off.

Check the app you are using

Communication apps keep their own device choice, which can differ from the Windows default. In Teams, Zoom, Discord, OBS or a game’s voice chat, open the audio or device settings and pick the same microphone you tested above. Also check the app’s own mute button and any push-to-talk setting. In a browser, the website needs permission too: Microsoft Edge asks per site, and you can review a site’s permissions from the site information icon at the left of the address bar.

Run the sound troubleshooter

Windows can check the input device for you. Go to Settings > System > Sound, scroll to Advanced, and under Troubleshoot common sound problems select Input devices. Follow the prompts in Get Help. It checks that the device is enabled, that it is the default, and that the audio services are running.

Fix the audio driver

If Windows does not detect the microphone, or the input disappeared after an update, reinstall the driver:

1. Right-click Start and select Device Manager.
2. Expand Sound, video and game controllers. Right-click the audio device, select Uninstall device, tick the option to remove the driver if offered, and select Uninstall.
3. Restart the PC. Windows reinstalls the audio device automatically.
4. If it does not, open Device Manager again, right-click Sound, video and game controllers and choose Scan for hardware changes.

You can also right-click the device and choose Update driver, or open Properties > Driver > Roll Back Driver if the problem started after a driver update. Laptops often need the audio driver from the maker’s support page for your model, because it includes the settings for the built-in microphone array. Check Audio inputs and outputs in Device Manager as well, and look for warning icons on any device listed there.

Test the microphone on another device

If none of this helps, plug the microphone or headset into another PC or a phone. If it fails there too, the hardware is faulty: a damaged cable is common with headsets. If it works elsewhere, the problem is in this PC. A new user account is a quick test of whether the problem is tied to your profile, and System Restore or Reset this PC with Keep my files rules out Windows completely. For a laptop’s built-in microphone under warranty, contact the PC maker.
