Microphone not working on Windows 11 and Windows 10
Windows blocks microphones silently — no error, no warning, just nothing. Here are the four places to look, in the order that resolves the most cases fastest.
Last reviewed on August 9, 2026
Windows has four separate places that can silence a microphone, and each of them looks identical from the outside: no sound, no error, nothing. This guide walks the four layers in the order that resolves the most cases fastest — privacy settings, device selection, levels and enhancements, then drivers. Every step applies to both Windows 10 and Windows 11, with the Windows 11 paths given first.
Two-minute version: Settings › Privacy & security › Microphone — turn on both "Microphone access" and "Let apps access your microphone". Then Settings › System › Sound › Input — pick the right device and check the level bar reacts when you speak. That fixes the majority of cases.
Step 1: Windows privacy settings
This is the most common cause on a Windows machine, and the most commonly missed, because Windows shows no warning when it is blocking access — applications simply receive silence.
Turn on Microphone access. This is the master switch for the whole device.
Turn on Let apps access your microphone.
Scroll down and turn on Let desktop apps access your microphone. Browsers count as desktop apps, and this switch being off is a classic cause of "my microphone works in Teams but not in Chrome".
Check the per-app list below and confirm your browser or app is enabled.
Verify with the microphone test before moving on. If the level meter now moves, you are done.
Step 2: Select the right input device
Windows laptops routinely expose several inputs — the internal array, a headset, a webcam microphone, and virtual devices installed by meeting software. Windows picks a default that is frequently not the one you want.
Open Settings › System › Sound.
Under Input, choose your device from the list.
Click the device to open its page, then speak. The Test your microphone bar should move.
If it does not move here, the problem is below the application layer — continue to step 3.
If it moves here but not in your browser, return to step 1, then reload the browser tab.
Hidden and disabled devices
A disabled recording device is invisible in the modern Settings app, which makes it look like the hardware has vanished:
Open Settings › System › Sound › More sound settings (Windows 10: right-click the speaker icon › Sounds).
Go to the Recording tab.
Right-click the empty area and tick Show Disabled Devices and Show Disconnected Devices.
If your microphone appears greyed out, right-click it and choose Enable, then Set as Default Device.
Step 3: Levels, mute, and enhancements
Still in the Recording tab, double-click your microphone to open its properties.
Levels tab. Check the speaker icon next to the slider — a crossed-out icon means the device is muted at driver level, which no application can override. Set the level to 70–80%.
Microphone Boost. If present, keep it at 0 dB or +10 dB. Higher values amplify room noise and hiss far more than your voice, and often push the signal into clipping.
Advanced tab. Untick Allow applications to take exclusive control of this device. Leaving it on lets one app lock everyone else out.
Enhancements tab (or "Audio enhancements" in Windows 11 device properties). Disable all effects temporarily. Noise suppression and acoustic echo cancellation can flatten a quiet microphone to silence.
Default Format. Set it to 2 channel, 16 bit, 48000 Hz. Exotic formats confuse some applications.
Vendor utilities add their own layer on top. Realtek Audio Console, Dolby Access, Nahimic, Waves MaxxAudio, and Lenovo/HP/Dell audio apps all have independent noise-suppression toggles that override Windows settings. If one is installed, open it and disable processing before concluding anything.
Step 4: Drivers
Driver problems are less common than the internet suggests, but they do occur after major Windows updates.
Right-click Start and open Device Manager.
Expand Audio inputs and outputs. A yellow warning triangle means a real driver fault.
Right-click your microphone and choose Uninstall device. Do not tick "delete the driver software" on the first attempt.
Choose Action › Scan for hardware changes. Windows reinstalls a working generic driver.
If that fails, download the audio driver directly from your laptop manufacturer's support page rather than from the chipset vendor. OEM drivers include the correct configuration for the internal microphone array.
Avoid "driver updater" utilities. They install generic drivers that frequently break the microphone array on laptops, replacing a working configuration with one that has no idea how the hardware is wired.
Step 5: Restart the audio services
If the microphone works after a reboot but fails again later, a stuck audio service is likely.
Press Win+R, type services.msc, press Enter.
Find Windows Audio, right-click, choose Restart.
Do the same for Windows Audio Endpoint Builder — this one rebuilds the device list and clears phantom entries.
Confirm both are set to Automatic startup.
Using the built-in troubleshooter
Windows includes a recording troubleshooter that is genuinely worth running once, mainly because it re-enables disabled devices and resets muted levels automatically. Open Settings › System › Troubleshoot › Other troubleshooters and run Recording Audio. Treat it as a quick automated pass over steps 2 and 3, not a substitute for them.
Laptop-specific causes
A physical mute key. Many business laptops have a microphone-mute function key with its own LED, entirely independent of Windows. Check the LED.
Hardware privacy shutters. Some Lenovo and HP models cut the microphone circuit electrically when the camera shutter is closed.
Combo jack confusion. One 3.5 mm port carries both output and input. A microphone-only plug or a three-conductor headphone plug will not present an input. Use a USB adapter or a proper TRRS plug.
Docking stations. Docks add their own audio device that becomes default on connection. Check what "default" points to after docking.
Managed work devices. Group Policy can disable microphone access outright, in which case nothing in this guide will help and IT has to change the policy.
If it still does not work
Isolate the layer that is failing:
Open the Windows Voice Recorder app. If it records, Windows is fine and the problem is in your browser or app — go to browser permissions.
If Voice Recorder also fails, the problem is below the app layer. Re-check steps 1 to 3.
Most often because Windows privacy settings block it. Open Settings, Privacy and security, Microphone, then enable Microphone access, Let apps access your microphone, and Let desktop apps access your microphone.
My microphone works in Teams but not in Chrome. Why?
The 'Let desktop apps access your microphone' switch is off. Browsers are classed as desktop apps, while Store apps like Teams use a separate permission.
Where is microphone boost in Windows 11?
Open Settings, System, Sound, More sound settings, Recording tab, then double-click your microphone and open the Levels tab. Keep boost at 0 or +10 dB — higher values amplify room noise more than your voice.
Should I use a driver updater tool?
No. Generic drivers frequently break laptop microphone arrays. Use Device Manager to reinstall, or download the audio driver from your laptop manufacturer's support page.
How do I restart Windows audio services?
Press Win+R, run services.msc, then restart both Windows Audio and Windows Audio Endpoint Builder. The second one rebuilds the device list and clears phantom entries.
My microphone works after a reboot then stops. Why?
Usually a stuck audio service or an application taking exclusive control. Untick 'Allow applications to take exclusive control of this device' in the microphone's Advanced properties.
