Laptop Microphone Not Working? Here’s What You Can Do 

Whether you’re jumping on a video call, recording a podcast, or attending an online class, your microphone plays a vital role in helping you be heard. But what happens when you plug in and speak up—and nothing happens? If your laptop microphone is not working, you’re not alone. Microphone issues are surprisingly frequent and can stem from various hardware or software glitches. 

Let’s walk through some of the most common reasons behind this problem and explore simple, step-by-step solutions to get your mic back in action. 

Why Is My Laptop Microphone Not Working? 

Before jumping into fixes, it’s helpful to understand the possible causes behind the issue. Here’s what might be going wrong: 

1. Software Glitches 

Sometimes, your system may not recognize the microphone due to a recent update or conflicting app permissions. 

2. Privacy Settings 

Modern operating systems like Windows and macOS have privacy controls that can restrict microphone access for specific apps or altogether. 

3. Outdated or Missing Drivers 

Microphone drivers help your system communicate with the hardware. If they’re corrupted or outdated, your mic might stay silent. 

4. Muted Input or Low Volume 

This is an easy one to miss. The microphone might not be muted, but the input volume could be turned down. 

5. External Devices Interfering 

If you use external mics, Bluetooth headsets, or USB devices, your laptop might prioritize them and ignore the internal mic. 

Quick Fixes to Try First 

Let’s start with the basics. Sometimes, the simplest solutions work best. 

1. Restart Your Laptop 

Sounds too simple? It often works. A quick reboot can fix temporary software bugs or conflicts that affect your mic. 

2. Check for External Devices 

Unplug all headphones, USB devices, or external microphones. Sometimes, your laptop routes audio input to these devices by default. 

3. Try Another App 

If your mic isn’t working in Zoom but works fine in Skype or Google Meet, the problem might be app-specific. Look into app-level settings. 

Step-by-Step Troubleshooting Guide 

Still no luck? Let’s break it down further based on your operating system. 

Windows 10/11 

Step 1: Check Privacy Settings 

1. Go to Settings > Privacy > Microphone 

2. Turn on Microphone access for this device 

3. Make sure Allow apps to access your microphone is switched on 

4. Scroll down and toggle on access for the apps you use (Zoom, MS Teams, etc.) 

Step 2: Adjust Sound Settings 

1. Right-click the speaker icon in the taskbar 

2. Click Sound settings 

3. Under Input, check if the correct microphone is selected 

4. Click on Device properties and adjust the volume slider 

Step 3: Update or Reinstall Drivers 

1. Right-click Start > Device Manager 

2. Expand the Audio inputs and outputs section 

3. Right-click on your microphone and select Update driver 

4. Choose Search automatically for drivers 

5. If it still doesn’t work, try Uninstall device and restart your system 

Step 4: Use Windows Troubleshooter 

1. Go to Settings > System > Troubleshoot > Other troubleshooters 

2. Run the Recording Audio troubleshooter 

3. Follow the on-screen instructions 

macOS 

If your Mac’s laptop microphone is not working, here’s what you can do: 

Step 1: Review Microphone Permissions 

1. Go to System Preferences > Security & Privacy > Privacy tab 

2. Click on Microphone 

3. Make sure your apps like Zoom, Skype, or Chrome are checked 

Step 2: Sound Input Settings 

1. Go to System Preferences > Sound > Input 

2. Select the internal microphone 

3. Speak and observe the input level meter—if it doesn’t move, try increasing the input volume 

4. If it still doesn’t work, switch to another mic (if available), then switch back 

Step 3: Reset PRAM and SMC (Intel Macs only) 

This can sometimes fix hardware-level issues: 

• Turn off your Mac 

• Hold Option + Command + P + R and power it on 

• Keep holding for 20 seconds 

• Release and let the Mac restart normally 

App-Specific Fixes 

Sometimes, your mic works fine, but just not with the app you’re using. Here’s how to fix that: 

Zoom 

• Go to Zoom Settings > Audio 

• Make sure the correct microphone is selected 

• Uncheck “Automatically adjust microphone volume” and set it manually 

Discord 

• Go to User Settings > Voice & Video 

• Select the correct input device 

• Click on Let’s Check to test your microphone 

Google Meet (Browser-based) 

• Click the lock icon in your Chrome address bar 

• Check that microphone access is set to Allow 

• Refresh the page and test again 

Hardware Checks to Consider 

If none of the software tweaks work, you might want to look into possible hardware issues. 

1. Run a Basic Mic Test 

Search for “voice recorder” in your system and record a sample. If there’s still no sound, the microphone itself might be faulty. 

2. Clean the Microphone Port 

Dust and debris near the mic grille can block sound. Use compressed air or a soft brush to clean it gently. 

3. Try an External Microphone 

Plug in a wired headset with a mic or a USB microphone. If this works, your internal mic might need repair. 

Advanced Fix: BIOS and System Settings 

This one’s a bit technical, but it could help if you’re still stuck. 

Check BIOS Settings 

Sometimes microphones are disabled at the BIOS level: 

1. Restart your laptop and press F2/F10/Del (depending on brand) 

2. Navigate to Advanced or Integrated Peripherals 

3. Look for an audio or microphone-related setting 

4. Make sure it’s enabled 

5. Save and exit 

When to Seek Professional Help 

If none of the above methods work and your laptop microphone is not working after every attempt, it might be time to visit a technician. Issues like: 

• A damaged audio chipset 

• A broken mic cable inside the laptop 

• Water or physical damage 

…require internal inspection and repair that professionals best handle.

• Handle your laptop with care to avoid dislodging internal mic connections 

• Avoid installing too many apps that can fight for microphone access 

• Run a quick mic check before joining important calls
