How to Fix Microphone Not Working on Windows 10: Troubleshooting Guide in 2026

Your microphone stopped working right when you needed it most. Whether you’re joining a video call, recording audio, or trying to use voice commands, a non-functional microphone disrupts everything. This guide walks you through every proven fix, from quick settings checks to advanced driver solutions.

Quick answer: Most microphone issues stem from disabled microphone access, incorrect default devices, or outdated drivers. Start by checking your privacy settings (Settings > Privacy > Microphone), then verify your device is set as default in Sound settings.

Let’s fix this systematically.

Check Windows 10 Microphone Privacy Settings

Windows 10 privacy controls can block apps from accessing your microphone entirely. This is the most common culprit in 2026.

Step-by-step process:

1. Press Windows key + I to open Settings
2. Navigate to Privacy > Microphone
3. Toggle “Allow apps to access your microphone” to ON
4. Scroll down and enable microphone access for specific apps you need (Chrome, Zoom, Discord, etc.)
5. Verify “Allow desktop apps to access your microphone” is also enabled

If this toggle was off, you’ve likely solved the problem. Test your microphone in the app you’re using.

Verify Your Microphone is the Default Recording Device

Windows might be listening to the wrong device. Your laptop has multiple audio inputs, and Windows doesn’t always choose correctly.

Set the correct default:

1. Right-click the speaker icon in your system tray
2. Select “Sounds”
3. Click the “Recording” tab
4. Look for your microphone in the list (it should show green bars moving when you speak)
5. Right-click your microphone and select “Set as Default Device”
6. Click “Set as Default Communication Device” as well
7. Click Apply, then OK

If you don’t see your microphone: Right-click in the empty space of the Recording tab and check both “Show Disabled Devices” and “Show Disconnected Devices.” If your microphone appears grayed out, right-click it and select “Enable.”

Test Microphone Input Levels

Even when enabled, your microphone might be muted or set too low to register sound.

Adjust input volume:

1. Open Sound settings (right-click speaker icon > Sounds)
2. Go to Recording tab
3. Double-click your microphone
4. Select the “Levels” tab
5. Ensure the volume slider is at 80-100%
6. Make sure the speaker icon next to the slider isn’t muted (no red circle with a line)
7. Click the “Advanced” tab
8. Uncheck “Allow applications to take exclusive control”
9. Click Apply

Speak normally and watch the green level meter. It should bounce with your voice. If it doesn’t move at all, continue troubleshooting.

Update or Reinstall Microphone Drivers

Corrupted or outdated drivers cause countless microphone failures. Windows Update doesn’t always catch audio driver issues.

Method 1: Update Through Device Manager

1. Right-click Start menu and select Device Manager
2. Expand “Audio inputs and outputs”
3. Right-click your microphone and select “Update driver”
4. Choose “Search automatically for updated driver software”
5. Let Windows search and install any updates
6. Restart your computer

Method 2: Reinstall the Driver

If updating didn’t work, a clean reinstall often fixes corruption:

1. Open Device Manager
2. Right-click your microphone under “Audio inputs and outputs”
3. Select “Uninstall device”
4. Check “Delete the driver software for this device” if the option appears
5. Click Uninstall
6. Restart your computer (Windows will reinstall the driver automatically)

Method 3: Download Manufacturer Drivers

Generic Windows drivers sometimes lack full functionality. Visit your computer manufacturer’s website (Dell, HP, Lenovo, etc.) or your microphone manufacturer’s site, download the latest audio drivers for your specific model, and install them directly.

For better guidance on driver updates, Microsoft’s official support documentation at https://support.microsoft.com provides model-specific instructions.

Run the Windows 10 Audio Troubleshooter

Windows includes a built-in diagnostic tool that automatically detects and fixes common audio problems.

Launch the troubleshooter:

1. Press Windows key + I
2. Go to Update & Security > Troubleshoot
3. Click “Additional troubleshooters”
4. Select “Recording Audio”
5. Click “Run the troubleshooter”
6. Follow the on-screen prompts

The troubleshooter checks for disabled devices, driver issues, and incorrect settings. It applies fixes automatically when possible. Pay attention to any problems it identifies but can’t fix automatically, then address those manually.

Disable Audio Enhancements

Windows audio enhancements sometimes interfere with microphone functionality, especially after updates.

Turn off enhancements:

1. Right-click speaker icon > Sounds
2. Recording tab
3. Double-click your microphone
4. Select “Enhancements” tab (or “Advanced” on some systems)
5. Check “Disable all sound effects” or “Disable all enhancements”
6. Click Apply > OK
7. Test your microphone

Check Physical Connections and Hardware

Software fixes only work if your hardware is properly connected.

For external microphones:

• Unplug and firmly reconnect the microphone jack (usually pink port)
• Try a different USB port if using a USB microphone
• Test the microphone on another computer to rule out hardware failure
• Check for a physical mute button or switch on the microphone itself
• Examine the cable for visible damage

For laptop built-in microphones:

• Clean the microphone hole gently with compressed air
• Check if a function key combination (Fn + F-key) mutes the microphone
• Some laptops have a physical privacy switch for the microphone

For Bluetooth microphones:

• Ensure Bluetooth is enabled in Windows settings
• Remove the device and re-pair it
• Check battery levels on the microphone
• Move closer to eliminate connection drops

Fix App-Specific Microphone Problems

Sometimes your microphone works in Windows but fails in specific applications.

Browser-Based Apps (Zoom, Google Meet, Discord Web)

1. Open your browser settings
2. Search for “microphone” or navigate to Privacy/Security settings
3. Ensure the browser has permission to access your microphone
4. Check site-specific permissions (click the padlock icon in the address bar)
5. Allow microphone access for the specific website

Chrome: Settings > Privacy and security > Site Settings > Microphone Firefox: Settings > Privacy & Security > Permissions > Microphone Edge: Settings > Cookies and site permissions > Microphone

Desktop Applications

Each app has its own audio settings. Open the app’s settings menu and look for Audio, Voice, or Microphone sections. Select your correct input device from the dropdown menu.

Common locations:

• Zoom: Settings > Audio > Microphone dropdown
• Discord: User Settings > Voice & Video > Input Device
• Skype: Settings > Audio & Video > Microphone
• Teams: Settings > Devices > Microphone
