Microphone Not Working on Windows 11
Nine fixes in the order that actually solves it most often, with the exact settings path for each one. Run the test on this page after every step so you know the moment it starts working.

On Windows 11 a microphone that has stopped working is almost never a broken microphone. In the overwhelming majority of cases it is one of three things: the privacy switch that controls whether apps may use the microphone at all, the wrong device selected as the default input, or an audio enhancement that is silently muting the signal.
Work through the steps below in order. They are arranged from most likely to least likely, and each one takes under a minute. Use the microphone test at the top of this page after each change — the level meter reacts instantly, so you will know immediately when the problem is gone rather than having to open a call and ask someone.
Fixes, in the order to try them
Check the physical mute first
Many headsets have a mute button on the cable or the earcup, and many USB microphones have a mute switch on the body. Some laptops have a keyboard shortcut with a microphone icon, often F4 or F8, that toggles mute at the hardware level. This costs five seconds to check and solves a surprising share of cases.
Turn on microphone access in Privacy settings
Open Settings, go to Privacy & security, then Microphone. Make sure “Microphone access” is On, then check that “Let apps access your microphone” is also On. Below that is a per-app list — scroll down and confirm the app you need is enabled. Browsers appear under “Let desktop apps access your microphone”, which is a separate switch further down the same page and is the one people miss most often.
Select the right input device
Open Settings, go to System, then Sound. Under Input, pick the microphone you are actually speaking into. Windows often switches to a monitor's built-in mic or a disconnected headset after an update. Speak while watching the volume bar next to the device — it should move.
Raise the input volume and check the boost
Still in Settings, System, Sound, click the input device to open its properties. Set Input volume to 100 and speak. If the level is still low, open the classic Sound control panel (search for “Change system sounds”, then the Recording tab), double-click your microphone, open the Levels tab, and raise Microphone Boost to +10 or +20 dB.
Turn off audio enhancements
In the same device properties, look for “Audio enhancements” and set it to Off. Windows enhancements and vendor packages such as Realtek or Waves MaxxAudio sometimes apply aggressive noise gates that cut speech entirely when the input is quiet. This is the single most common cause of a microphone that works in Windows' own test but produces silence in apps.
Close whatever else is using it
Windows lets several apps share a microphone, but drivers for some interfaces and headsets take exclusive control. Fully quit Zoom, Teams, Discord, OBS, Skype and any browser tab that had microphone access, then try again. Check the system tray, because these apps commonly keep running after the window is closed.
Run the built-in troubleshooter
Open Settings, go to System, then Troubleshoot, then Other troubleshooters, and run “Recording Audio”. It genuinely fixes device-selection and service problems, and it takes about a minute. If it reports that a service is not running, let it apply the fix.
Restart the Windows Audio service
Press Windows+R, type services.msc and press Enter. Find “Windows Audio”, right-click it and choose Restart. Do the same for “Windows Audio Endpoint Builder”. If either is set to anything other than Automatic startup, change it. A stalled audio service produces exactly the symptoms of dead hardware.
Reinstall the audio driver
Press Windows+X and open Device Manager. Expand “Audio inputs and outputs”, right-click your microphone and choose Uninstall device. Do not tick the box to delete the driver software. Restart the computer — Windows reinstalls a working driver automatically. If the mic is part of a headset or an interface, download the current driver from the manufacturer rather than relying on Windows Update.
Why the privacy setting catches so many people
Windows keeps two separate microphone permissions and they are easy to confuse. The upper switch controls Microsoft Store apps. Further down the same page is “Let desktop apps access your microphone”, which governs everything installed the traditional way — including Chrome, Firefox, Discord, Zoom and OBS.
A Windows feature update can reset either one. The symptom is distinctive: the microphone appears and works in Windows' own sound settings, where the level bar moves normally, but every application receives silence. If that matches what you are seeing, this is your problem.
When it is genuinely a hardware fault
Hardware faults are rarer than people expect, but three patterns point to one. If the microphone fails identically on a second computer, the device is at fault. If a 3.5 mm headset works in a phone but not in the laptop, the combo jack or its detection circuit is suspect. And if the microphone works only when you hold the cable at a particular angle, the cable has broken internally near the connector, which no setting will fix.
One more distinction worth knowing: many laptops use a single combo jack for headphones and microphone. A four-pole headset plug works there, but a standard three-pole microphone plug does not carry a microphone signal at all on that jack. If you are plugging a desktop microphone into a laptop's only audio port, that is why nothing is heard.
Getting sound but nobody can hear you clearly
If the meter on this page moves but callers complain, the problem has shifted from “no signal” to “bad signal”, and the fixes are different. A very low level means you should raise the input volume and enable boost. A harsh, crackling voice means the level is too high and clipping — reduce it. A hollow, distant sound usually means Windows selected the laptop's array microphone instead of your headset.
Echo is its own case: it means your microphone is picking up your speakers. Wearing headphones removes it instantly, and our echo and feedback guide covers the rest.
Other fix guides
If this was not your problem, one of these probably is. Each guide covers a different platform or application, with the exact settings path for that one:
Microphone Not Working on Windows 11 — FAQ
Why did my microphone stop working after a Windows 11 update?
Feature updates frequently reset the privacy switches and change the default input device. Check Settings, Privacy & security, Microphone first — including the separate switch for desktop apps — then Settings, System, Sound to confirm the right input is selected.
My microphone works in Windows settings but not in any app.
That pattern almost always means the “Let desktop apps access your microphone” switch is off, or an audio enhancement is gating the signal. Both are covered in steps 2 and 5 above.
How do I test my microphone on Windows 11?
Settings, System, Sound, then click your input device and use “Start test”. The test at the top of this page does the same thing without leaving your browser, and adds a recording so you can hear yourself.
Where is Microphone Boost in Windows 11?
It is in the old Sound control panel rather than the new Settings app. Search for “Change system sounds”, open the Recording tab, double-click your microphone, then open the Levels tab.
Does Windows 11 have a microphone privacy shortcut?
Some laptops include a function key with a crossed-out microphone icon that mutes at the hardware level, independent of Windows settings. Check for one before assuming a software fault.
Nothing worked — what now?
Test the same microphone on a phone or another computer. If it fails there too, the device is faulty. If it works, the problem is specific to the Windows installation, and a system restore to a point before the fault appeared is usually faster than continuing to chase settings.
