Microphone Not Working? Fix Your Mic Step by Step

How to use it

Start the check and allow microphone access if your browser asks.
Speak for a few seconds while the checks run.
Find the first X and follow the fix shown for your system and browser.
Run the check again, then try the full mic test to hear how you sound.

What the mic troubleshooter checks

The tool runs a chain of checks in order and marks each one with a check mark or an X. The first X is usually the real cause, so fix that one first.

Check	What a failure means
Browser support	The browser can't use microphones; update it or try another browser
Secure connection	Browsers allow microphones only on HTTPS pages
Permission	Shown as allowed, blocked or not asked yet. Blocked means someone said no earlier
Microphones found	How many inputs the browser sees, with names. Zero points to the system, driver or cable
Can it open?	The mic exists but won't start, often because another app is holding it
Signal in 5 seconds	The mic opened but sends silence: mute switch, wrong device or a system privacy block
Level	Silent, very quiet, good or clipping (too loud)

The tool detects your operating system and browser and shows only the steps that apply, plus tips for Zoom, Teams and Discord. On Windows and Mac, a quick link opens the right system settings page (your browser asks first). Browser settings addresses such as chrome://settings/content/microphone can't be opened from a web page, so you get a copy button instead. Everything runs in your browser; nothing you say is saved or uploaded.

Mic not working on Windows 11 or Windows 10

1. Privacy settings. On Windows 11, open Settings > Privacy & security > Microphone and turn on Microphone access, Let apps access your microphone and Let desktop apps access your microphone. The last switch is easy to miss, and it covers desktop browsers and call apps. On Windows 10, go to Settings > Privacy > Microphone, select Change to turn on Microphone access for this device, then turn on both app switches below it.

2. Input device. Go to Settings > System > Sound and, under Input, choose your mic in Choose a device for speaking or recording. Open its properties to check the Input volume slider and run Start test. If the wrong device is the default, apps may be listening to a webcam mic or an unplugged headset.

3. Drivers. Right-click Start and open Device Manager. Look under Audio inputs and outputs and Sound, video and game controllers. If your mic shows a down-arrow icon, right-click it and choose Enable device. Otherwise try Update driver, or Uninstall device and restart so Windows reinstalls it.

Mic not working on a Mac

On macOS Ventura and later, choose Apple menu > System Settings > Privacy & Security > Microphone and turn on your browser or call app. An app shows up in this list only after it has asked for the microphone at least once. If you change the setting while the browser is open, quit and reopen it.

Then go to System Settings > Sound > Input, select the right microphone and watch the input level while you speak. Raise Input volume if the level barely moves. When an app is using the mic, an orange dot appears in the menu bar; open Control Center to see which app it is.

Unblock the microphone in your browser

Chrome: click the icon to the left of the address bar, turn on Microphone (or open Site settings and choose Allow), then reload the page. To see all sites and pick the default mic, go to chrome://settings/content/microphone (Settings > Privacy and security > Site settings > Microphone).
Edge: click the lock icon left of the address bar, open Permissions for this site and set Microphone to Allow. All sites are listed at edge://settings/content/microphone.
Firefox: a crossed-out microphone icon in the address bar means the site is blocked. Click it, clear the block and reload. For all sites: Settings > Privacy & Security > Permissions > Microphone > Settings.
Safari on Mac: choose Safari > Settings for [site name] and set Microphone to Allow, or use Safari > Settings > Websites > Microphone.

If you clicked Block once, the browser won't ask again until you change it here.

iPhone, Android and Chromebook

iPhone and iPad: for Safari, go to Settings > Safari (Settings > Apps > Safari on iOS 18 and later) > Microphone and choose Ask or Allow. For Chrome or another app, go to Settings > Privacy & Security > Microphone and turn that app on.
Android: in Chrome, tap the icon left of the address and open Permissions, or go to ⋮ > Settings > Site settings. Then check the app itself: Settings > Apps > Chrome > Permissions > Microphone. On Android 12 and later, also open Quick Settings and make sure the Microphone access tile is on; when it is off, apps receive only silence. Menu names vary a little between phone makers.
Chromebook: open Settings > Privacy and security > Privacy controls and turn on Microphone access. To pick the input, open Quick Settings, select the arrow next to the volume slider and choose your mic under Input.

Other apps, mute buttons and headsets

Another app has the mic. Zoom, Teams, Discord, OBS or a recording app can hold the microphone. Quit them fully (check the system tray or menu bar) and run the check again.
Wrong device inside the app. Zoom: Settings > Audio. Teams: Settings > Devices. Discord: User Settings > Voice & Video > Input Device. Each app keeps its own choice, separate from your system default.
Hardware mute. Headsets often have a mute switch on the cable or ear cup. Many laptops have a mic-mute key with a crossed-out microphone icon, sometimes with a small light.
Bluetooth headsets switch to a lower-quality call mode while the mic is on. If the mic stays silent, remove the pairing and pair again.

Once every check passes, run the full mic test to hear how you sound. Camera trouble too? Use the camera troubleshooter.

Frequently asked questions

Why is my microphone not working in Chrome?

Usually the site is blocked in Chrome, or the system blocks Chrome. Click the icon left of the address bar and allow the microphone. On Windows, also turn on Let desktop apps access your microphone; on a Mac, enable Chrome in Privacy & Security > Microphone.

Why does my mic work in other apps but not in the browser?

The browser needs its own permission for each site, and it may use a different default input than your other apps. Check the site permission and the microphone selected in the browser's settings.

How do I turn on my microphone in Windows 11?

Open Settings > Privacy & security > Microphone and turn on Microphone access, Let apps access your microphone and Let desktop apps access your microphone. Then choose your device in Settings > System > Sound > Input.

The mic is allowed but nobody can hear me. What now?

Check for a mute switch on the headset or a mic-mute key on the laptop, make sure the right input is selected, and raise the input volume. On Android 12 and later, check the Microphone access tile in Quick Settings.

Does the troubleshooter record my voice?

No. It only measures whether a signal arrives and how loud it is, inside your browser. Nothing is saved or uploaded.

My mic works, but people say I sound quiet. How do I fix that?

Raise the input volume in your system sound settings, move the mic closer, then check the level and record a sample with the mic test.
