Fixing Computer Microphone Not Working

A functioning microphone is essential for seamless communication, be it for video conferencing, online classes, gaming, or recording audio. However, technical difficulties can sometimes render your computer’s microphone inoperable. This extensive guide provides a comprehensive approach to troubleshooting and resolving microphone issues on your computer, ensuring smooth and reliable communication.

1. Check Microphone Permissions

Permissions are crucial for microphone functionality, especially on modern operating systems that prioritize user privacy.

  • For Windows 10/11: Go to Settings > Privacy & Security > Microphone. Here, you’ll see a list of apps with access to your microphone. Make sure the apps you want to use with the microphone are allowed access. Additionally, check the overall access permission at the top to ensure apps can access the microphone.
  • For macOS: Open System Preferences > Security & Privacy > Privacy tab. Click on Microphone from the sidebar and review the apps listed. Ensure that the checkbox next to the applications you use is ticked to grant them microphone access.

2. Test Microphone Functionality

Testing your microphone can quickly help you determine if the issue is software-related or if there’s a problem with the microphone itself.

  • Use built-in tools like Windows’ Voice Recorder or macOS’s QuickTime Player to record a quick audio clip. If you can record and playback your voice, the microphone is working.
  • If you’re troubleshooting for specific applications like Skype or Zoom, use their respective audio test features to ensure the microphone is picked up within the app.

3. Update Audio Drivers

Outdated or incorrect audio drivers can lead to microphone malfunctions. Ensuring you have the latest drivers can resolve these issues.

  • Windows: Use Device Manager to find your audio device, right-click on it, and select “Update driver.” You can let Windows search automatically or browse your computer for driver software if you’ve downloaded the latest drivers from the manufacturer’s website.
  • macOS: macOS typically updates drivers automatically through system updates. Check for any available system updates in System Preferences > Software Update and install them to ensure all drivers are up to date.

4. Adjust Microphone Settings

Fine-tuning your microphone settings can enhance its performance and solve volume-related issues.

  • In the Sound settings (Windows) or Sound preferences (macOS), you can adjust the input volume or sensitivity of the microphone. Increasing the volume can help if your microphone input is too quiet.
  • Check for any enhancements or noise suppression options that might be affecting microphone quality and adjust them according to your needs.

5. Troubleshoot Microphone Hardware Issues

Hardware issues can range from simple connection problems to physical damage.

  • Ensure the microphone is securely connected to the correct port. If it’s a USB microphone, try different ports to rule out a faulty USB port.
  • Examine the microphone and its cable for any visible signs of wear or damage. Sometimes, the issue might be as simple as a frayed wire that needs replacement.

6. Disable Conflicting Applications

Applications running in the background can sometimes take control of the microphone and cause conflicts.

  • Use the Task Manager (Windows) or Activity Monitor (macOS) to close any non-essential applications that might be using the microphone.
  • Check for any recently installed software that could interfere with your microphone’s operation and consider uninstalling it to see if that resolves the issue.

7. Perform System Restore

A system restore can revert your computer’s settings back to a point when everything was working correctly.

  • Windows: Go through the System Restore process cautiously, selecting a restore point created before the microphone issues began. This action can undo recent changes that might be causing the problem.
  • macOS: While macOS doesn’t have a system restore feature similar to Windows, you can use Time Machine backups to restore your system to a previous state.

8. Check for System Updates

Keeping your system up-to-date is crucial for device compatibility and functionality.

  • Regularly check for updates in your system settings and install them to ensure all system components and drivers are current.

9. Reset Sound Settings

Resetting sound settings can clear any misconfigurations causing issues.

  • Look for an option to reset all sound settings to their defaults within your system’s audio settings. This can help clear any incorrect settings that might be causing microphone issues.

10. Consult Online Forums and Communities

Online tech forums and communities can be invaluable resources for troubleshooting.

  • Platforms like Reddit, Stack Exchange, and manufacturer-specific forums often have users who have encountered similar issues and can provide solutions based on their experiences.


By following the comprehensive steps outlined in this guide, you should be able to resolve most microphone issues on your computer. If the microphone remains dysfunctional, it might be necessary to contact your computer manufacturer or a professional technician for further assistance.
