If your microphone isn't working in Windows 11, it can be frustrating—especially during calls or recordings. The issue might stem from hardware, drivers, settings, or permissions. Here’s how to fix it step by step.

1. Check Physical Connections and Hardware
Before diving into software fixes, rule out hardware problems:
- For external mics: Unplug and reconnect the microphone. Try a different USB port.
- For headsets: Make sure the headset is properly plugged into the correct audio jack (if using 3.5mm).
- Test on another device: Plug the mic into a phone or another computer to confirm it works.
- Try a different microphone: If possible, test with another mic to see if the issue is with the device itself.
If the mic works elsewhere, the problem is likely with Windows settings or drivers.

2. Set the Correct Input Device in Windows
Windows might be using the wrong microphone input.
- Right-click the speaker icon in the taskbar and select Settings.
- Go to System > Sound.
- Under Input, check the Input device dropdown.
- Select the correct microphone (e.g., "Microphone (Realtek Audio)" or your headset).
- Speak into the mic and watch the input level bar—if it moves, Windows is detecting sound.
? If your mic doesn’t appear in the list, it may not be detected at all—proceed to driver troubleshooting.

Windows 11 includes a built-in tool to detect and fix common audio problems.
- Go to Settings > System > Sound.
- Scroll down and click Troubleshoot common sound problems.
- Follow the prompts and let Windows scan for issues.

Apps like Teams, Zoom, or Chrome won’t access the mic if permissions are blocked.

- Make sure Microphone access is turned on.
- Scroll down and ensure Let apps access your microphone is enabled.
- Check that the specific app you're using (e.g., Zoom) has permission listed under Let apps access your microphone.
? Some apps require permission even if system access is on—open the app and check its audio settings.
5. Update or Reinstall Audio Drivers
Outdated or corrupted drivers are a common cause.
Option A: Update via Device Manager
- Press Win X and select Device Manager.
- Expand Audio inputs and outputs.
- Right-click your microphone (e.g., "Microphone Array") and choose Update driver.
- Select Search automatically for drivers.
Option B: Reinstall the driver
- In Device Manager, right-click the mic and choose Uninstall device.
- Restart your PC—Windows will reinstall the driver automatically.
Option C: Update from manufacturer
- Visit your PC or motherboard manufacturer’s website (e.g., Dell, HP, ASUS).
- Download the latest audio driver (e.g., Realtek) for your model.
6. Enable the Microphone in BIOS/UEFI (if applicable)
Some laptops disable the internal mic by default or after a BIOS update.
- Restart your PC and enter BIOS/UEFI (usually by pressing F2, F10, or Del during boot).
- Look for Integrated Peripherals or Onboard Devices.
- Ensure Internal Microphone or Audio Device is set to Enabled.
- Save and exit.
7. Check for Windows Updates
Microsoft often releases patches for audio issues.
- Go to Settings > Windows Update.
- Click Check for updates.
- Install any available updates and restart.
8. Additional Fixes if Nothing Works
-
Disable audio enhancements:
- In Sound settings, click More sound settings under Advanced.
- Go to the Recording tab, right-click your mic, select Properties.
- On the Advanced tab, check Disable all enhancements.
- Also, uncheck Allow applications to take exclusive control.
Test in another app: Try using the mic in Voice Recorder, Discord, or Chrome (test mic at webcammictest.com).
Roll back driver: If the mic stopped working after a driver update, go to Device Manager > Microphone > Driver > Roll Back Driver.
Fixing a non-working mic in Windows 11 usually comes down to settings, permissions, or drivers. Start with the basics—check connections and input selection—then work through permissions and drivers. Most issues can be resolved without needing professional help.
