A laptop microphone that suddenly stops working can prevent you from joining video meetings, recording audio, using voice typing, or chatting through apps such as Zoom, Teams, Discord, and other communication programs. The problem may be caused by muted microphone settings, incorrect input devices, disabled permissions, outdated drivers, software conflicts, or a hardware issue.
Fortunately, many microphone problems can be fixed with a few simple checks.
Common Reasons a Laptop Microphone Is Not Working
Your laptop microphone may stop working because of:
- Microphone is muted
- Wrong microphone is selected
- Windows microphone permissions are disabled
- App does not have microphone access
- Microphone volume is too low
- Audio driver is outdated or corrupted
- Windows audio services have stopped
- Another application is controlling the microphone

20 Ways to Fix a Laptop Microphone That Is Not Working
1. Check the Microphone Mute Button
Many laptops have a dedicated microphone mute key or a function-key shortcut.
Look across the keyboard for a microphone icon. If the microphone key has an indicator light, make sure it is not showing that the microphone is muted.
Press the microphone mute key once and test the microphone again.
2. Check the App’s Microphone Settings
If the microphone works in one application but not another, the problem may be inside the application.
Open the affected app and look for:
Settings → Audio → Microphone/Input Device
Make sure the correct laptop microphone is selected.
Also check whether the microphone is muted inside the application.
3. Make Sure Windows Is Using the Correct Microphone
Windows may automatically switch to another input device.
Go to:
Settings → System → Sound → Input
Under the input section, select your built-in laptop microphone.
Speak normally and watch the input level. If the level moves, Windows is receiving sound.
4. Increase Microphone Volume
A microphone can appear to work while its input level is extremely low.
Go to:
Settings → System → Sound → Input
Select your microphone and increase the input volume.
Test it again by speaking close to the laptop.
5. Allow Microphone Access in Windows
Privacy settings can prevent applications from accessing your microphone.
Go to:
Settings → Privacy & security → Microphone
Make sure:
- Microphone access is enabled
- Apps are allowed to access your microphone
- Desktop apps are allowed to access your microphone
After changing these settings, restart the affected application.
6. Test the Microphone in Windows
Windows includes a simple microphone test.
Go to:
Settings → System → Sound → Input
Select your microphone and use the available test option.
Speak normally and check whether Windows detects your voice.
If there is no response at all, continue with the driver and hardware checks below.
7. Restart the Laptop
A temporary Windows audio problem can sometimes stop the microphone from working.
Save your work, close your applications, and restart the laptop.
After Windows loads again, open the application and test the microphone.
8. Disconnect Headphones and External Microphones
If a headset, USB microphone, or Bluetooth device is connected, Windows may automatically select it instead of the built-in microphone.
Disconnect external audio devices and test the laptop microphone again.
If the built-in microphone starts working, check your external device separately.
9. Check Bluetooth Audio Devices
A connected Bluetooth headset can become the default microphone.
Open:
Settings → Bluetooth & devices
Temporarily disconnect Bluetooth headphones or earbuds.
Then return to:
Settings → System → Sound → Input
Select the built-in microphone and test it.
10. Run the Windows Audio Troubleshooter
Windows can automatically detect certain audio configuration problems.
Go to:
Settings → System → Troubleshoot → Other troubleshooters
Look for the available audio troubleshooter and run it.
Follow the recommended fixes and test the microphone afterward.
11. Update the Microphone Driver
An outdated or damaged driver can prevent Windows from communicating correctly with the microphone.
Open:
Device Manager → Audio inputs and outputs
Find your microphone, right-click it, and select:
Update driver
Follow the instructions provided by Windows.
12. Reinstall the Microphone Driver
If updating the driver does not help, reinstalling it may resolve corrupted driver files.
In Device Manager:
- Expand Audio inputs and outputs
- Right-click the microphone
- Select Uninstall device
- Restart the laptop
- Allow Windows to detect the device again
If your laptop manufacturer provides a specific audio driver, you can also install the appropriate driver from the manufacturer’s official support page.
13. Check the Microphone in Device Manager
The microphone may have been disabled.
Open Device Manager and check:
Audio inputs and outputs
Look for your microphone.
If it is disabled, enable the device and restart the audio application.
Also look for a warning icon that could indicate a driver problem.
14. Restart Windows Audio Services
Windows audio services are responsible for handling sound input and output.
Press:
Windows + R
Type:
services.msc
Press Enter.
Find Windows Audio and check that the service is running.
If necessary, restart the service and test your microphone again.
15. Close Applications That May Be Using the Microphone
Another program may already be accessing the microphone.
Close applications such as:
- Zoom
- Microsoft Teams
- Discord
- Skype
- Web browsers
- Voice recording software
- Game chat applications
Then open only the application you want to test.
16. Check Browser Microphone Permissions
If your microphone doesn’t work on websites but works elsewhere, browser permissions may be responsible.
For example, a browser may have blocked microphone access for a meeting or recording website.
Open the website’s permission settings and make sure microphone access is allowed.
Then refresh the page and test again.
17. Install Pending Windows Updates
Windows updates can include audio-driver and compatibility fixes.
Go to:
Settings → Windows Update
Check for available updates.
Install important updates and restart the laptop if requested.
If the microphone stopped working immediately after a major update, also check whether the laptop manufacturer provides a newer audio driver.
18. Check for Physical Obstructions or Damage
The built-in microphone is usually located near the webcam, display bezel, keyboard, or another small opening.
Check that the microphone opening is not blocked by:
- Dust
- Dirt
- Tape
- A laptop cover
- Protective material
Clean the area gently without pushing anything into the microphone opening.
If the laptop was dropped, exposed to liquid, or physically damaged before the microphone stopped working, hardware damage is possible.
19. Test With an External Microphone
Connect a known-working USB microphone or headset.
If the external microphone works but the built-in microphone does not, the built-in microphone or its connection may have a hardware problem.
If neither microphone works, Windows settings, drivers, or another software issue is more likely.
20. Get Professional Help for Persistent Hardware Problems
If you have tried the software fixes and the built-in microphone still produces no input, the microphone itself may be faulty.
Professional inspection may be necessary if:
- The laptop was dropped
- Liquid entered the laptop
- The microphone disappeared from Device Manager
- The microphone suddenly stopped after hardware damage
- Multiple microphones fail
- The audio system has other hardware problems
Avoid opening the laptop unless you are experienced with laptop hardware repair.
