Summary

This guide helps you troubleshoot and resolve: How to fix Windows 11 microphone not working in Teams, Zoom, and other apps. Follow the steps below to fix the issue.

Common Causes

If your microphone is not working in Windows 11 during Teams, Zoom, or other applications, the cause is usually a privacy setting, an incorrect default device, or a driver problem. This guide walks you through the most effective fixes, starting with the quickest checks and moving to more detailed troubleshooting.

Quick Fix Steps

Try these first. They resolve most microphone issues in under a minute.

1. Check that your microphone is not physically muted. Many headsets and laptops have a hardware mute button or switch.
2. Unplug and reconnect your microphone or headset. If it uses USB, try a different USB port.
3. Restart your computer. A reboot clears temporary glitches that can block audio input.
4. In your meeting app, click the microphone icon to ensure you are not muted within the app itself.
5. If you use a Bluetooth headset, turn Bluetooth off and on again, then reconnect the device.

Detailed Instructions

1. Check Windows Privacy Settings

Windows 11 can block microphone access for all apps or for specific apps. This is the most common cause of a microphone working in one app but not another.

1. Open Settings by pressing Windows key + I.
2. Click Privacy & security in the left sidebar.
3. Under App permissions, click Microphone.
4. Ensure Microphone access is turned On.
5. Ensure Let apps access your microphone is turned On.
6. Scroll down to the list of apps. Find Microsoft Teams, Zoom, or whichever app is affected, and make sure its toggle is On.
7. If the app does not appear in the list, open the app once, then return to this page and check again.

2. Set the Correct Default Microphone

Windows may be listening to the wrong input device, such as a webcam microphone instead of your headset.

1. Open Settings > System > Sound.
2. Under Input, click the dropdown next to Choose a device for speaking or recording.
3. Select the microphone you want to use. If you are unsure, speak into your preferred microphone and watch which device shows activity in the list.
4. Click the device name (not the dropdown) to open its properties.
5. Under Input settings, set the Input volume slider to at least 80.
6. Click Start test and speak. The test should register your voice.

3. Check App-Specific Audio Settings

Each video conferencing app has its own microphone selection that can override the Windows default.

Microsoft Teams

1. Open Teams and click the three dots (…) next to your profile picture.
2. Select Settings > Devices.
3. Under Microphone, select the correct device from the dropdown.
4. Speak and check the Microphone level indicator below the dropdown.
5. If the indicator does not move, click Make a test call to diagnose further.

Zoom

1. Open Zoom and click the gear icon in the top-right corner.
2. Select Audio in the left sidebar.
3. Under Microphone, select the correct device from the dropdown.
4. Click Test Mic and speak. You should hear your voice played back.
5. Ensure Automatically join audio by computer when joining a meeting is ticked if you want to use the computer microphone by default.

Other apps

Most applications have an audio or devices section in their settings. Look for a microphone dropdown and select the correct device. If the app uses the Windows default device, changing the Windows default (section 2) will also change it in the app.

4. Update or Reinstall Audio Drivers

A corrupted or outdated audio driver can prevent the microphone from working entirely.

1. Right-click the Start button and select Device Manager.
2. Expand the Audio inputs and outputs section.
3. Right-click your microphone and select Update driver.
4. Click Search automatically for drivers.
5. If Windows finds an update, install it and restart your computer.
6. If no update is found, right-click the microphone again and select Uninstall device.
7. Tick Attempt to remove the driver for this device if prompted, then click Uninstall.
8. Restart your computer. Windows will automatically reinstall the driver.

5. Run the Windows Recording Audio Troubleshooter

Windows includes a built-in diagnostic tool that can automatically detect and fix common microphone problems.

1. Open Settings > System > Troubleshoot.
2. Click Other troubleshooters.
3. Find Recording Audio in the list and click Run.
4. Follow the on-screen prompts. The troubleshooter may ask you to select a device or perform a test.
5. Apply any recommended fixes and restart your computer if prompted.

6. Disable Audio Enhancements

Audio enhancements can sometimes interfere with microphone input, especially on Realtek and other onboard audio chipsets.

1. Open Settings > System > Sound.
2. Under Input, click your microphone device.
3. Scroll down and look for Audio enhancements.
4. If the setting is available, set it to Off.
5. Test your microphone again in the affected app.

7. Check for Windows Updates

Microsoft regularly releases fixes for audio issues through Windows Update.

1. Open Settings > Windows Update.
2. Click Check for updates.
3. Install any available updates, including optional driver updates under Advanced options > Optional updates.
4. Restart your computer after updates are installed.

Troubleshooting Specific Scenarios

Microphone works in some apps but not others

This almost always points to app-specific permissions. Revisit the Privacy & security > Microphone settings and verify the affected app is toggled on. Also check the app's own audio settings to ensure it is not set to use a different microphone.

Microphone is detected but no sound is picked up

If Windows shows the microphone as connected but the test bar does not move, try the following:

1. Check the physical mute switch on your microphone or headset.
2. Increase the Input volume slider in Settings > System > Sound > Input.
3. Disable audio enhancements as described in section 6.
4. Update or reinstall the audio driver as described in section 4.

Bluetooth microphone not working

Bluetooth microphones can be particularly troublesome. Try these steps:

1. Remove the Bluetooth device from Windows: Settings > Bluetooth & devices > click the three dots next to the device > Remove device.
2. Put the headset into pairing mode and pair it again.
3. After pairing, ensure the headset is set as the default input device in Settings > System > Sound.
4. In your meeting app, select the Bluetooth headset as the microphone.
5. If the problem persists, check the manufacturer's website for firmware updates.
