Quick Answer

Run the free mic test first. If the level meter moves, your hardware is fine — the problem is browser permissions or app settings. If the meter does not move, check Windows Privacy settings (Settings → Privacy & Security → Microphone) and confirm your input device is selected in Sound Settings.

Step-by-Step Fix (works for 95% of issues)

Test your mic first — isolate hardware from software

Before changing any settings, confirm whether your microphone hardware is actually broken. Run the free mic test below — if the level meter moves when you speak, the hardware is fine and the problem is a permission, driver, or app-settings issue.

Run Free Mic Test →

Check browser permissions (Chrome, Firefox, Edge)

Click the padlock icon in your browser's address bar. Set Microphone to Allow and reload the page. In Chrome, also check chrome://settings/content/microphone — the site must not be in the Blocked list.

Browser Permission Check →

Enable mic access in Windows Privacy settings

Go to Settings → Privacy & Security → Microphone. Turn on 'Microphone access' and 'Let desktop apps access your microphone.' Without this, no app — not even Chrome — can use your mic.

Select the correct input device

Windows sometimes switches your Default input device when you plug in headphones or a USB mic. Open Settings → System → Sound → Input and confirm the right device is selected. Do the same inside Zoom (Settings → Audio) or Teams (Settings → Devices).

Disable WASAPI Exclusive Mode

If your mic works in one app but not another, one app is locking the device. Go to Sound Settings → Input → Device Properties → Additional device properties → Advanced tab → uncheck 'Allow applications to take exclusive control of this device.'

Update or reinstall audio drivers

Open Device Manager → expand 'Audio inputs and outputs' → right-click your microphone → Update driver. If updating doesn't help, Uninstall device and restart — Windows will reinstall a clean driver automatically.
