• Microphone works in some apps but not others

Fix 1: Check Microphone Permissions

Windows 11 has strict privacy settings that prevent apps from accessing the microphone by default. If apps can't use your mic, check these permissions.

Step 1. Press Win + I to open Settings.

Step 2. Go to "Privacy & security" > "Microphone".

Step 3. Make sure "Microphone access" is turned on.

Step 4. Make sure "Let apps access your microphone" is turned on.

Step 6. Also check "Let desktop apps access your microphone" if your app is a desktop app.

Fix 2: Set Default Microphone

If you have multiple microphones, Windows might be using the wrong one. Set the correct microphone as default.

Step 1. Press Win + R, type mmsys.cpl, and press Enter.

Step 2. Go to the "Recording" tab.

Step 3. Find your microphone (e.g., "Microphone (Realtek Audio)" or "Headset Microphone").

Step 4. Right-click it and select "Set as Default Device".

Step 5. Also right-click and select "Set as Default Communication Device" if available.

Step 6. Right-click any disabled microphones and select "Enable" if you want to use them.

Windows 11 has a built-in troubleshooter for recording audio that can automatically detect and fix common microphone issues.

Step 1. Press Win + I to open Settings.

Step 2. Go to "System" > "Troubleshoot" > "Other troubleshooters".

Step 3. Find "Recording Audio" and click "Run".

Step 4. Wait for the troubleshooter to scan for issues. It will try to fix them automatically.

Fix 4: Update or Reinstall Microphone Drivers

Outdated or corrupted audio drivers are a common cause of microphone issues. Updating or reinstalling them usually fixes the problem.

Update Audio Drivers

Step 1. Press Win + X and select "Device Manager".

Step 2. Expand "Audio inputs and outputs" or "Sound, video and game controllers".

Step 3. Right-click your microphone or audio device and select "Update driver".

Step 4. Choose "Search automatically for drivers" and follow the prompts.

Step 2. Go to the "Recording" tab.

Step 3. Right-click your microphone and select "Properties".

Step 4. Go to the "Levels" tab.

Step 7. If you're using a headset with a physical mute button or in-line controls, make sure it's not muted.

Fix 6: Disable Audio Enhancements

Audio enhancements can sometimes cause microphone issues, especially with third-party audio software. Disabling them can help.

Microsoft regularly releases audio driver updates through Windows Update. Make sure your Windows 11 is up to date.

Step 1. Press Win + I to open Settings.

Step 7. Click "Yes" to confirm and restart your PC.

Fix 9: Check Physical Connections

For external microphones, check the physical connections.

Step 1. If using a USB microphone, try a different USB port (preferably a USB 2.0 port instead of USB 3.0 if you're having issues).

Step 2. If using a 3.5mm jack microphone, make sure it's plugged into the correct port (usually pink or with a microphone icon). Don't plug it into the headphone jack.

Step 3. If using a Bluetooth headset, make sure it's paired and connected. Try removing and re-pairing it.

Step 4. If using a headset with a built-in microphone, make sure the cable is fully inserted.

Step 5. Try the microphone on another device to rule out a hardware issue.

FAQs About Windows 11 Microphone Issues

Why is my microphone not working in Windows 11?

Common causes include microphone permissions being disabled, incorrect default device selected, outdated or corrupted drivers, or physical connection problems. Check microphone permissions first (Fix 1), then try setting the correct default device.

How do I allow apps to access my microphone in Windows 11?

Go to Settings > Privacy & security > Microphone. Turn on "Microphone access", "Let apps access your microphone", and toggle on the specific apps you want to use. Also turn on "Let desktop apps access your microphone" for desktop applications.

Why is my microphone not detected?

If your microphone doesn't appear in Settings or Device Manager, it may be a hardware issue or a driver problem. Check physical connections, try a different port, and update or reinstall the audio drivers.

Why is my microphone volume so low?

Go to Settings > System > Sound > Input, and increase the input volume. Also open mmsys.cpl > Recording tab > Microphone > Properties > Levels tab, and set the volume to 100. If it's still low, try the "Microphone Boost" option if available.

Why does my Bluetooth headset microphone not work?

Bluetooth headsets often have two modes: "Stereo" (high-quality audio, no mic) and "Hands-Free" (lower-quality audio with mic). Make sure your headset is set to "Hands-Free AG Audio" mode when you need to use the microphone. Go to Settings > System > Sound and select the correct output and input devices.

Back Up and Restore Windows with Qiling Disk Master

Before you reinstall the audio driver, change privacy permissions, or restart sound services, create a full system backup. Audio fixes touch shared drivers and services, so a system image gives you a clean rollback if your microphone setup breaks. Qiling Disk Master handles both the backup and the restore.

Part 1: Create a Full System Backup

Step 1. Install and open Qiling Disk Master. On the home screen, open "Backup and Recovery" and choose "System Backup". This option automatically includes Windows and the hidden boot partitions, so you do not have to select them one by one.

Step 2. Check the source. The disk where Windows is installed and its system partitions are already ticked for you. If you only need your personal documents, run a separate "File Backup" task instead.

Step 3. Click the destination box and choose where the image should be saved. Use an external HDD or SSD, a NAS, or any drive other than the one you are about to repair, and make sure it has enough free space.

Step 4. Review the task summary and click "Proceed". Wait until the progress bar reaches 100%. Do not unplug the drive or turn off the PC while the backup is running.

Part 2: Restore Windows from the Backup

Step 1. Open Qiling Disk Master again, go to "Backup and Recovery", and select the recovery option. Your backup images are listed, so pick the one you created before the repair.

Step 2. Choose the target disk or partition. Normally you restore to the original system disk. If the drive was replaced, select the new disk instead, and the restore rebuilds Windows together with its boot partitions.

Step 3. Preview the restore plan, click "Proceed", and confirm the warning. The PC restarts to finish the job, and Windows comes back exactly as it was on the day the image was created.

Conclusion

Windows 11 microphone not working is usually fixable by checking microphone permissions, setting the correct default device, or updating the audio drivers. If the issue persists, run the recording audio troubleshooter, disable audio enhancements, or check physical connections. For Bluetooth headsets, make sure to use the "Hands-Free" mode. For most users, one of these fixes will resolve the issue.
