How to Test a Microphone on Windows 10

To test a microphone on Windows 10, open Start > Settings > System > Sound, select the microphone under Input, and speak at a normal volume. Watch the Test your microphone meter. If it moves, Windows is receiving audio from the mic. If the meter works but a calling, recording, or browser app does not, the problem is usually the app's selected input or microphone permission rather than the microphone itself.

Important: Microsoft ended standard support for Windows 10 on October 14, 2025. Existing Windows 10 PCs still run, but Microsoft recommends moving to a supported version of Windows or using an eligible Extended Security Updates option. This guide is for PCs that are still running Windows 10. See Microsoft's Windows 10 end-of-support guidance.

Test your microphone in Windows 10 Settings

1. Make sure the microphone, headset, webcam, or USB audio device is connected and not muted by a physical switch.
2. Open Start > Settings > System > Sound.
3. Under Input, choose the microphone you want to test from Choose your input device.
4. Speak into the microphone and watch Test your microphone. A moving bar means Windows is detecting your voice.

If the bar moves only a little, select Device properties and check the microphone level. On Windows 10, the classic Microphone Properties dialog can also expose Microphone and, on supported hardware, Microphone Boost controls. Raise levels gradually; excessive boost can add hiss or background noise. Microsoft's current microphone troubleshooting page documents the Windows 10 input test and level controls.

Use the Recording tab for a second Windows test

The classic Sound control panel is useful when you want to confirm that Windows sees the correct recording device independently of a specific app. Open Control Panel, choose Hardware and Sound > Sound, then open the Recording tab. You can also right-click the speaker icon on some Windows 10 builds and open Sounds.

Select your microphone and speak. The green level meter beside the device should rise and fall. If you have several microphones, identify the one whose meter reacts, then set it as the default recording device if that matches how you use the PC.

If a microphone appears here but shows no activity, check its Properties, confirm it is enabled, and inspect the Levels tab. If it does not appear at all, move to the hardware and driver checks below.

If Windows hears the mic but an app does not

A successful Windows meter test means the microphone and basic audio path are working. The next things to check are Windows privacy permissions and the app's own input selection.

• Open Start > Settings > Privacy > Microphone.
• Make sure microphone access for the device is enabled and Allow apps to access your microphone is on.
• For Microsoft Store apps, allow the specific app you need. For traditional desktop programs, make sure Allow desktop apps to access your microphone is on.
• Inside the calling, streaming, or recording app, choose the same microphone that worked in Windows. Some apps keep their own input-device setting instead of following the Windows default.

Microsoft explains the Windows 10 permission controls in its microphone app-permissions guide. Browser-based meeting sites can also have a separate site permission for the microphone, so check the browser's address-bar permission if only one website fails.

If Windows does not detect any microphone input

When the Windows input meter never moves, start with the simplest causes. Reseat a 3.5 mm plug, try another USB port, charge or reconnect a Bluetooth headset, and verify any inline mute button. If your PC has separate headphone and microphone jacks, make sure the plug or headset adapter matches the ports on the computer.

Next, open Device Manager. Check Audio inputs and outputs for the microphone, and check Sound, video and game controllers for the audio device or driver. If the hardware is missing, use Action > Scan for hardware changes. If Windows detects the device but it still does not work, update or reinstall the audio driver using Windows' device tools or the PC/audio-device manufacturer's official driver package.

You can also run the Windows 10 Recording Audio troubleshooter from Settings > Update & Security > Troubleshoot > Additional troubleshooters. It can catch common configuration problems such as an incorrect input device or disabled recording path.

How to interpret the result

• The Windows meter moves and the app works: the microphone is functioning normally.
• The Windows meter moves but one app fails: check that app's microphone selection and permissions.
• The microphone appears but no meter moves: check mute status, position, levels, and the physical connection.
• The microphone does not appear anywhere: focus on the port, Bluetooth pairing, USB connection, hardware detection, and audio driver.

Testing in this order separates a Windows-level microphone problem from an app-specific one, which makes the next troubleshooting step much clearer.
