Windows 11 Microphone Not Working? How to Fix It

A microphone can stop working because Windows selected the wrong input device, an app lost permission, the microphone is muted, its input volume is too low, the audio driver is damaged, or another program has taken control of it. External USB, Bluetooth and 3.5 mm microphones can also fail because of their connection, power or compatibility.

The right fix depends on whether Windows can detect the microphone at all. I recommend starting with the test below before changing drivers or resetting anything.

Test Whether Windows 11 Can Hear Your Microphone

Windows 11 includes a microphone test that helps separate a system-wide problem from an app-specific one.

1. Press Windows + I to open Settings.
2. Select System.
3. Open Sound.
4. Scroll to Input.
5. Select the microphone you want to use.
6. Under Input settings, select Start test.
7. Speak normally for several seconds.
8. Select Stop test.
9. Play the recorded sample.

If the sample contains your voice, the microphone and Windows audio system are working. Focus on the settings inside Teams, Zoom, Discord, a game, browser or other affected application.

If the recording is silent, distorted or unavailable, continue with the system fixes below.

Microsoft’s current Windows microphone troubleshooting instructions also recommend selecting the correct input device, testing it from Sound settings and checking app permissions.

Check the Microphone and Its Connection

Before changing Windows settings, inspect the microphone itself.

For a laptop microphone:

• Look for a microphone mute key on the keyboard.
• Check whether its indicator light shows that the microphone is muted.
• Open any physical privacy control supplied by the laptop manufacturer.
• Remove a case, cover or debris blocking the microphone openings.

For a wired headset or microphone:

• Disconnect and reconnect the plug firmly.
• Try another compatible port.
• Check the mute switch on the cable or headset.
• Confirm that the microphone uses the correct connector.
• Test it on another computer or phone when possible.

Many desktop PCs have separate headphone and microphone jacks. A headset with one combined four-pole plug may need a headset splitter before its microphone works with separate green and pink ports.

For a USB microphone:

• Connect it directly to the computer instead of an unpowered hub.
• Try another USB port.
• Wait for Windows to finish installing the device.
• Check whether the microphone requires its own power or control software.

If the microphone does not work on another compatible device, the problem is probably hardware-related rather than a Windows 11 setting.

Make Sure the Microphone Is Not Muted

A microphone can be muted in several places at the same time. Check:

• The headset or microphone hardware switch
• A laptop microphone-mute key
• Windows input settings
• The application you are using
• A meeting or game mute control
• The manufacturer’s audio utility

Open Settings > System > Sound, select the microphone under Input and check its volume control. If a muted speaker or microphone symbol appears, unmute it.

Also look at the taskbar while the app is using the microphone. Windows may display a microphone privacy indicator in the notification area.

Select the Correct Input Device

Windows can automatically select a webcam, monitor, game controller, Bluetooth headset or virtual audio device instead of the microphone you intended to use.

1. Open Settings > System > Sound.
2. Find Input.
3. Open Choose a device for speaking or recording.
4. Select the correct microphone.
5. Speak and watch the input-level meter.

Disconnect devices you are not using if their names make the list confusing. Virtual microphones installed by streaming, voice-changing or noise-cancellation software can also become the default input.

After selecting the device in Windows, open the affected app and choose the same microphone in its audio settings. Some applications ignore the Windows default and remember a different device.

Turn On Microphone Permissions

Windows 11 can detect and test a microphone while still preventing an app from using it.

1. Open Settings.
2. Select Privacy & security.
3. Under App permissions, select Microphone.
4. Turn on Microphone access.
5. Turn on Let apps access your microphone.
6. Enable access for the affected Microsoft Store app.
7. Turn on Let desktop apps access your microphone.

Traditional desktop applications do not always appear with individual switches. The main desktop-app permission must be enabled for programs such as classic meeting clients, games and recording software.

If the app uses a camera that contains a microphone, also check Settings > Privacy & security > Camera. Some video-calling applications require both permissions.

Turn the relevant permission off and back on if it already appears enabled, close the affected app completely and reopen it.

Set the Microphone as the Default Recording Device

Some older programs use the default device selected in the classic Sound panel rather than the microphone shown at the top of modern Settings.

1. Open Settings > System > Sound.
2. Scroll down and select More sound settings.
3. Open the Recording tab.
4. Right-click the microphone you want to use.
5. Select Set as Default Device.
6. If available, also select Set as Default Communication Device.
7. Select Apply, then OK.

The default communication device is commonly used by calling and meeting software. The general default device may be used by recording tools and other applications.

Enable a Disabled Microphone

An input device may be installed but disabled.

1. Open Settings > System > Sound > More sound settings.
2. Select the Recording tab.
3. Right-click an empty area in the device list.
4. Enable Show Disabled Devices and Show Disconnected Devices.
5. Right-click the disabled microphone.
6. Select Enable.
7. Set it as the default device if necessary.

You can also check Settings > System > Sound > All sound devices. Select the microphone and use the Allow control if Windows shows that apps and Windows are blocked from using it.

Increase the Microphone Input Volume

If the microphone works but other people can barely hear you, raise its input level.

1. Open Settings > System > Sound.
2. Select the microphone under Input.
3. Increase Input volume gradually.
4. Run the microphone test again.

Do not immediately set every control to 100 percent. Very high gain can introduce static, distortion, keyboard noise and echo.

Some sound drivers also provide Microphone Boost:

1. Open More sound settings.
2. Select the Recording tab.
3. Double-click the microphone.
4. Open Levels.
5. Increase the Microphone level.
6. Add a small amount of Microphone Boost if available.
7. Select Apply and test again.

Not every microphone or driver provides a boost control.

Check the Microphone Inside the Affected App

If the Windows test works, avoid reinstalling the driver immediately. Check the app first.

Open the application’s audio or voice settings and confirm:

• The correct microphone is selected.
• The app is not muted.
• Input volume is high enough.
• Push-to-talk is not enabled unintentionally.
• The correct push-to-talk key is assigned.
• Automatic sensitivity is not setting the threshold too high.
• Noise suppression is not removing your voice.
• The app is not using a virtual microphone.

Use the application’s test-call or mic-test feature when available.

If only one app has the problem, reset its audio settings, install its latest stable update or reinstall that app. A system-wide driver change is rarely the best first response when every other program records correctly.

Allow Microphone Access in the Browser

A browser can block microphone access even when Windows permissions are correct.

When a website requests the microphone:

1. Select the lock or permissions icon beside the address bar.
2. Find Microphone.
3. Change it to Allow.
4. Reload the page.

Also open the browser’s site-permission settings and confirm that the correct input device is selected. Remove an old block rule for the website if necessary.

Test another supported browser. If the microphone works there, the issue is likely a permission, extension or profile setting in the original browser.

Close Apps That May Be Using the Microphone

Recording software, communication programs, game launchers and browser tabs can remain active in the background.

Close applications that may use audio input, including:

• Teams
• Zoom
• Discord
• OBS Studio
• Voice changers
• Screen recorders
• Game chat clients
• Browser tabs with microphone permission
• Manufacturer audio utilities

Open Task Manager with Ctrl + Shift + Esc and end only the affected user applications. Do not terminate random Windows audio processes.

Reopen one program and test the microphone. If it works, add the other applications back one at a time to identify the conflict.

Turn Off Exclusive Control

Windows can allow an application to take exclusive control of an audio device. This can improve some professional audio workflows, but it may prevent another program from using the microphone correctly.

1. Open Settings > System > Sound > More sound settings.
2. Select the Recording tab.
3. Double-click the microphone.
4. Open Advanced.
5. Clear Allow applications to take exclusive control of this device.
6. Clear Give exclusive mode applications priority if it appears.
7. Select Apply.
8. Restart the affected apps.

If you use professional recording software that requires exclusive mode, note the original settings before changing them.

Disable Audio Enhancements

Noise cancellation, beam forming, echo control and other enhancements can improve recording quality, but a faulty driver or incompatible effect can make the microphone silent or distorted.

1. Open Settings > System > Sound.
2. Select the microphone.
3. Find Audio enhancements.
4. Set it to Off.
5. Test the microphone.

The option may instead appear in More sound settings > Recording > Microphone Properties > Enhancements. Select Disable all enhancements when that control is available.

If turning enhancements off fixes the problem, leave them disabled or update the laptop, motherboard, headset or audio driver before enabling them again.

Change the Default Audio Format

An app may not work correctly with the format currently assigned to the microphone.

1. Open More sound settings.
2. Select Recording.
3. Double-click the microphone.
4. Open Advanced.
5. Choose another supported Default Format.
6. Select Apply.
7. Test the microphone.

Start with a common format offered by the device, such as 16-bit, 44.1 kHz or 48 kHz. Available formats depend on the microphone and driver.

Avoid changing many advanced controls simultaneously. Test after each adjustment so you know which one solved the problem.

Reconnect a Bluetooth Microphone

A Bluetooth headset can appear connected while Windows uses the laptop microphone or no working input at all.

1. Charge the headset.
2. Turn it off and back on.
3. Open Settings > Bluetooth & devices > Devices.
4. Confirm that the headset is connected.
5. Open Settings > System > Sound.
6. Select the headset microphone under Input.
7. Run the microphone test.

Make sure the headset is not actively connected to another phone, tablet or computer. Multipoint Bluetooth devices can route the microphone unexpectedly.

If pairing appears corrupted, remove the headset and pair it again. My guide on removing a Bluetooth device that will not disconnect from Windows 11 can help if Windows refuses to delete the old pairing.

Bluetooth headsets may switch to a communication profile when the microphone is active. This can reduce playback quality during a call and does not necessarily mean the headset is damaged.

Run the Windows 11 Audio Troubleshooter

Current Windows 11 versions use the Get Help troubleshooting system for many audio problems.

1. Open Settings > System > Sound.
2. Scroll to Advanced.
3. Under Troubleshoot common sound problems, select Input devices.
4. Follow the Get Help instructions.
5. Apply only fixes relevant to the detected microphone.

You can also open the Get Help app and search for microphone or audio-input troubleshooting.

The troubleshooter may check permissions, device status, drivers and audio services. Restart Windows after it applies a change.

Restart Windows Audio Services

Windows Audio and Windows Audio Endpoint Builder support recording and playback devices. Restarting them can clear a stuck audio session.

1. Press Windows + R.
2. Enter services.msc.
3. Select OK.
4. Find Windows Audio.
5. Right-click it and select Restart.
6. Find Windows Audio Endpoint Builder.
7. Restart it.
8. Confirm that both services use their normal automatic startup settings.

Restart the computer and test the microphone again.

Do not disable these services. Doing so can remove both input and output audio from Windows.

Check the Microphone in Device Manager

Device Manager shows whether Windows recognises the microphone and its audio components.

1. Right-click Start.
2. Select Device Manager.
3. Expand Audio inputs and outputs.
4. Look for the microphone.
5. Expand Sound, video and game controllers.
6. Look for the computer’s Realtek, Intel, AMD, USB, Bluetooth or manufacturer audio device.

A warning icon can indicate a driver or hardware problem. If the microphone does not appear, select Action > Scan for hardware changes after reconnecting it.

For hidden or disconnected entries, select View > Show hidden devices. Do not uninstall every faded audio entry unless you understand which device it represents.

Update the Microphone or Audio Driver

A damaged or incompatible driver can prevent Windows 11 from detecting input.

1. Open Device Manager.
2. Expand Audio inputs and outputs.
3. Right-click the microphone.
4. Select Update driver.
5. Choose Search automatically for drivers.

Repeat the check under Sound, video and game controllers for the main audio device.

Also visit Settings > Windows Update > Advanced options > Optional updates and check for an appropriate audio-driver update.

For a laptop or prebuilt PC, the manufacturer’s support page is often the best source for the tested audio package. Use the exact computer model and Windows version. For a custom desktop, check the motherboard or microphone manufacturer’s official support page.

Avoid generic driver-download websites. An incorrect audio package can remove jack detection, microphone boost, noise cancellation or other device-specific controls.

Reinstall the Audio Driver

If the driver is present but appears corrupted:

1. Open Device Manager.
2. Expand Audio inputs and outputs.
3. Right-click the affected microphone.
4. Select Uninstall device.
5. Confirm the removal.
6. Restart Windows.

Windows may reinstall a compatible driver automatically.

If the problem continues, uninstall the related device under Sound, video and game controllers, restart the PC and install the official audio package supplied by the device or computer manufacturer.

Create a restore point and download the replacement driver before removing a manufacturer package. This is especially important when the computer has no alternative internet connection.

Roll Back a Recent Audio Driver

If the microphone stopped working immediately after a driver update:

1. Open Device Manager.
2. Expand Sound, video and game controllers.
3. Double-click the relevant audio device.
4. Open the Driver tab.
5. Select Roll Back Driver.
6. Choose the applicable reason.
7. Restart Windows.

The button is unavailable when Windows has no previous driver package to restore.

Do not roll back unrelated graphics, network or chipset drivers merely because the microphone failed. Identify the audio device involved first.

Install Windows Updates

Microsoft and hardware manufacturers release fixes for device compatibility and audio components through Windows Update.

1. Open Settings.
2. Select Windows Update.
3. Select Check for updates.
4. Install the available stable updates.
5. Restart the computer.
6. Test the microphone.

If the problem began immediately after a Windows update, first complete any pending updates and restart. An incomplete servicing cycle can leave drivers in an inconsistent state.

Only consider removing a recent update when the timing clearly points to it and ordinary microphone, permission and driver fixes have failed.

Repair Windows System Files

Damaged Windows components can affect Settings, privacy permissions, Device Manager and audio services.

Open Windows Terminal as administrator and run:

DISM /Online /Cleanup-Image /RestoreHealth

Allow it to finish. Then run:

sfc /scannow

Restart Windows after both commands complete.

If SFC returns an error instead of completing, use the appropriate steps in my Windows Resource Protection error guide rather than repeatedly running the same command.

Test with a Clean Boot

A clean boot starts Windows with Microsoft services and a limited set of startup programs. It can reveal conflicts caused by audio utilities, voice changers, security software or recording tools.

1. Press Windows + R.
2. Enter msconfig.
3. Open the Services tab.
4. Select Hide all Microsoft services.
5. Select Disable all.
6. Open the Startup tab.
7. Select Open Task Manager.
8. Disable nonessential startup applications.
9. Restart the computer.
10. Test the microphone.

Do not clear Hide all Microsoft services before choosing Disable all. Disabling core Windows services can create additional problems.

If the microphone works during a clean boot, re-enable items in groups until you identify the conflict. Restore normal startup after testing.

Safe Mode is less useful for ordinary microphone testing because it may not load the normal audio drivers and services. However, it can help when you need to remove a conflicting driver or application. If necessary, follow my Windows 11 Safe Mode instructions.

Fix a Built-In Laptop Microphone That Is Missing

When the internal microphone does not appear anywhere in Windows:

1. Check the keyboard microphone-mute key.
2. Open the manufacturer’s privacy or audio utility.
3. Install the official audio and chipset drivers for the laptop model.
4. Check Device Manager for disabled or unknown devices.
5. Run the manufacturer’s hardware diagnostics.
6. Check the BIOS or UEFI only if the manufacturer provides a microphone or onboard-audio setting.

Some laptops use an Intel Smart Sound Technology component alongside a Realtek or other codec. Installing only one part of the official audio package may leave the internal microphone unavailable.

If an external microphone works but the built-in one does not, the internal microphone array, cable or related hardware may require professional service.

Microphone Works but Sounds Quiet, Robotic or Distorted

A microphone that records poor audio is different from one that is completely undetected.

Try these adjustments:

• Lower an excessive input volume or boost level.
• Move closer to the microphone.
• Disable audio enhancements temporarily.
• Try another default format.
• Remove nearby electrical interference.
• Connect a USB microphone directly to the PC.
• Stop multiple noise-suppression tools from processing the same input.
• Check the sample rate inside professional recording software.
• Update the official device driver or firmware.

For Bluetooth headsets, reduced playback quality while the microphone is in use can be a limitation of the active Bluetooth audio profile. Test a USB or wired headset when you need simultaneous high-quality playback and microphone input.

Microphone Works in Windows but Not in Teams, Zoom or Discord

When the Windows microphone test succeeds:

1. Open the app’s audio settings.
2. Select the same microphone tested in Windows.
3. Check its mute and input-volume controls.
4. Disable push-to-talk for testing.
5. Run the app’s test call.
6. Check Windows microphone permissions.
7. Close other calling or recording software.
8. Reset the app’s voice settings.
9. Update or reinstall the affected app.

For a browser-based meeting, check both the browser’s site permission and the meeting website’s own microphone selector.

If the app recently added AI noise removal, voice isolation or echo cancellation, turn that feature off temporarily. Aggressive filtering can interpret a quiet voice as background noise.

Microphone Stops Working After Sleep

Power management can leave a USB or Bluetooth microphone disconnected after Windows wakes.

1. Disconnect and reconnect the microphone.
2. Turn a Bluetooth headset off and back on.
3. Restart the affected app.
4. Check for computer, USB, Bluetooth and audio-driver updates.
5. Test another USB port.

For a USB device, open Device Manager, find the relevant USB hub, open its Power Management tab when available and test clearing Allow the computer to turn off this device to save power.

Change this only for the hub or device involved. Disabling power management across every USB controller can increase power consumption and battery drain.

Frequently Asked Questions

Why is my microphone not working on Windows 11?

The most common causes are a muted microphone, incorrect input-device selection, blocked app permission, low input volume, a loose connection, an app-specific setting or a damaged audio driver.

How do I enable my microphone in Windows 11?

Open Settings > Privacy & security > Microphone and enable Microphone access and app access. Then open Settings > System > Sound and select the microphone under Input.

How do I test my microphone?

Open Settings > System > Sound, select the microphone, choose Start test, speak normally, stop the test and play the recorded sample.

Why does Windows detect my microphone but apps cannot use it?

The app may lack permission, have the wrong input selected or be muted. Enable microphone access under Privacy & security and select the same input inside the app.

Why is my headset microphone not showing?

The headset may be connected to the wrong jack, require a splitter, be muted, use an incomplete Bluetooth profile or need a manufacturer driver. Test another port and check Device Manager.

Why did my microphone stop working after a Windows update?

The update may have changed privacy settings, selected another default input or installed an incompatible audio driver. Check permissions and device selection before updating, reinstalling or rolling back the driver.

Can I reinstall the microphone driver?

Yes. Remove the affected device through Device Manager and restart Windows. For laptops and specialised microphones, install the official audio package from the computer or device manufacturer afterward.

Why is my microphone volume so low?

Input volume or Microphone Boost may be low, the microphone may be too far away, or noise suppression may be reducing your voice. Increase levels gradually and test after each change.

Why does my Bluetooth headset sound worse when I use its microphone?

Windows may switch the headset to a communication profile that supports both input and output with reduced playback quality. A wired or USB connection may provide better simultaneous audio quality.

Should I reset Windows to fix the microphone?

Not initially. Microphone problems are usually resolved through hardware checks, permissions, input selection, app settings or driver repair. A full reset is excessive unless Windows has broader unresolved problems.

Start with the Windows microphone test because it immediately shows whether the problem affects the whole system or only one application. If Windows cannot record your voice, work through the connection, permissions, input selection, volume and driver fixes in that order. When Windows records correctly, focus on the affected app rather than making unnecessary system changes.
