Microphone Not Working in Windows
Nobody can hear you in calls or your recordings are silent. Here is how to get your microphone working again in Windows 10 and 11.

Microphone problems in Windows fall into a few categories: privacy settings blocking access, the wrong input device being selected, a driver issue, or the mic being physically muted. Here is how to work through them.
Check the Privacy Settings
This is the most commonly missed step. Windows has privacy controls that can block apps from using the microphone entirely.
- Go to Settings > Privacy & security > Microphone (Windows 11) or Settings > Privacy > Microphone (Windows 10).
- Make sure Microphone access is turned on at the top.
- Scroll down and confirm that the specific app (Teams, Discord, Zoom, the Voice Recorder) also has permission.
Check the Default Recording Device
Right-click the speaker icon in the system tray and choose Sound settings. Under Input, check that the correct microphone is selected. If you have more than one listed (headset mic, built-in mic, USB mic), try each one.
Alternatively, right-click the speaker icon, choose Sounds, go to the Recording tab, and confirm that your microphone is set as the Default Device. Right-click it and choose Set as Default Device if it is not.
Test the Microphone Level
On the Recording tab, speak into the microphone — the green bars beside the device should move. If there is no movement at all, either the device is not receiving audio or the volume is turned down. Right-click the microphone entry, choose Properties, go to the Levels tab, and raise the microphone volume. Also check that the microphone is not muted using the mute icon on the same tab.
Check for a Physical Mute Button
Many headsets, USB microphones, and some laptop keyboards have a dedicated mute button. Check the device itself and look along the keyboard's function row for a mic icon.
Update the Audio Driver
Open Device Manager, expand Audio inputs and outputs, right-click the microphone entry, and choose Update driver. Restart the PC afterwards and retest.
Run the Recording Audio Troubleshooter
Go to Settings > System > Troubleshoot > Other troubleshooters and run Recording Audio. Windows often detects and automatically corrects driver or service issues.
If the microphone shows up in device list and levels move but apps cannot hear you, ask us — there are app-specific fixes that may apply.
Frequently asked questions
My microphone works in Windows but not in one specific app. What should I do?
First confirm that app has microphone permission in Windows Privacy settings (Settings > Privacy & security > Microphone). Then open the app's own audio settings and make sure your microphone is selected as the input device within that app — many calling and recording apps have their own independent audio device selection that overrides the Windows default.
My microphone picks up my voice but others say there is a constant background hiss. Can I fix that?
Open Sound settings, go to the Recording tab, right-click your microphone, choose Properties, then the Enhancements tab. Enable Noise Suppression or Noise Cancellation if available. Also check that the microphone volume level is not set too high (above 80 often increases noise). Dedicated apps such as NVIDIA RTX Voice or Krisp can provide stronger noise cancellation if the built-in option is not sufficient.
