Microphone not working? Windows 11 usually blocks it in one of three places. Check Settings → Privacy & security → Microphone and turn on Microphone access, Let apps access your microphone and Let desktop apps access your microphone.
Then open Settings → System → Sound and make sure the right mic is picked under Input. Still silent? Run the sound troubleshooter, then reinstall the audio driver in Device Manager.
A dead mic usually isn’t a broken mic. It’s a privacy switch, the wrong input device, or a volume slider set to zero. Work through the fixes below in order. The early ones take seconds and solve most cases. Before you start, test the mic with our free mic test so you know whether the problem is the microphone itself or just one app.
Why is my microphone not working? Windows 11 causes to check first
- Privacy settings are blocking it. Windows has a master switch and separate switches for Store apps and desktop apps. One switch off is enough to silence a mic.
- The wrong input device is selected. A webcam, a monitor or a headset you used last week may have taken over as the default.
- The input volume is very low or muted.
- The app has its own device setting. Zoom, Teams, Discord and browsers each pick a microphone, and they don’t always follow Windows.
- A hardware mute. Many headsets have a mute button or a flip-up boom that mutes the mic.
- A driver problem, often after a Windows update or a new device.
1. Check the physical basics
Start with the easy things. Check the headset’s mute button or mute light. Unplug a USB mic and plug it into a different port. For a wired headset with separate plugs, Microsoft notes that the pink jack is the input and green is the output. If your laptop has a mic mute key, press it once and watch for a light to change. Menu names and key locations can differ by model.
2. Turn on microphone access in privacy settings
This is the fix most people miss. Microsoft’s support page lists it first.
- Select Start → Settings → Privacy & security → Microphone.
- Turn on Microphone access.
- Turn on Let apps access your microphone, then check that the app you’re using is switched on in the list below it.
- Turn on Let desktop apps access your microphone. Browsers, Zoom, Discord and most programs you install from a website are desktop apps.
Microsoft says desktop apps may not always appear in that list. That’s normal. The Let desktop apps access your microphone switch still controls them.
3. Pick the right input device
- Select Start → Settings → System → Sound.
- Under Input, use Choose a device for speaking or recording and pick your microphone.
- Speak and watch the volume bar next to it. If it moves, Windows can hear you.
If you see several similar entries, such as a webcam mic and a headset mic, pick the one you actually want to talk into. Then check the same choice inside your app.
4. Raise the input volume and run a mic test
- In Settings → System → Sound, select your microphone under Input (or the > arrow next to it) to open its properties.
- Move the Input volume slider up. Very low values make you sound silent to other people.
- Under Microphone test, select Start test, speak normally, then select Stop test and check the result.
Our browser-based mic test shows a live level meter and lets you record a short clip and play it back. If it works there but not in a call, the problem is the app, not Windows.
5. Check the setting inside the app
Video and chat apps keep their own audio settings. Open the app’s settings, find the audio or voice section, and choose the same microphone you picked in Windows. In a browser, the site also needs permission. Look for the camera or mic icon in the address bar and allow the microphone for that site. Close other apps that might be using the mic, then try again.
6. Run the sound troubleshooter
Windows 11 has a built-in troubleshooter for audio problems. Open Settings → System → Sound, scroll to the Advanced section and select the option to troubleshoot common sound problems. You can also go to Settings → System → Troubleshoot → Other troubleshooters and select Run next to Audio. Follow the prompts, and let it apply any fixes it suggests.
7. Update Windows and restart
Go to Settings → Windows Update and select Check for updates. Install what’s offered, including driver updates, then restart the PC from Start → Power → Restart. A full restart clears more than waking the PC from sleep.
8. Reinstall the audio driver
- Right-click Start and select Device Manager.
- Expand Sound, video and game controllers.
- Right-click your audio device and select Uninstall device.
- Restart the PC. Windows reinstalls the driver when it starts up.
- If the device doesn’t come back, open Device Manager again, right-click Sound, video and game controllers and select Scan for hardware changes.
Only uninstall the audio device you’re fixing. If you’re unsure which entry is which, update the driver first and leave uninstalling as a later step.
9. Rule out the microphone itself
Plug the headset or USB mic into another computer or a phone. If it fails there too, the mic or its cable is faulty. If it works elsewhere, the problem is on your PC, so go back through the privacy and driver steps.
If it still doesn’t work
- Mic works in one app only: it’s that app’s audio setting or permission. Reset its audio settings or reinstall it.
- Mic stopped after an update: check for another update, then reinstall the driver as in step 8.
- Work or school PC: your organization may control microphone access. Ask your IT team before changing anything.
- Others hear you, but faintly: raise the input volume and move the mic closer. Turn off noise-cancelling options in the app one at a time to see which helps.
