How to Unmute Your Mic in Windows 11

To unmute your microphone in Windows 11, open Settings > System > Sound, find your microphone under Input, and select the microphone icon next to Volume so it no longer shows a line through it. Then check the two other places a mic is often muted: the app you’re using, such as Teams or Zoom, and any mute key or switch on your keyboard or headset. In supported apps, Windows key + Alt + K toggles mute.

Applies to: Windows 11 with built-in, USB, Bluetooth or headset microphones. Last reviewed October 7, 2026.

Method 1: Unmute in Settings

1. Press Windows key + I and select System > Sound.
2. Under Input, check that the right microphone is selected in Choose a device for speaking or recording.
3. Next to Volume, select the microphone icon to unmute it, and drag the slider up to around 70 to 100.
4. Speak and watch the blue bar under Test your microphone or Input volume move.

If the microphone shows Don’t allow, select it and set Audio to Allow. That option turns a device off for all apps.

Method 2: Use the keyboard

• Windows key + Alt + K mutes and unmutes your mic in calls in supported apps, such as Microsoft Teams. A microphone icon appears on the taskbar while a call is active; select it to toggle mute too.
• Many laptops have a microphone key, often on F4 or F8, with a crossed-out mic icon and sometimes a light that shows it’s muted. Press it, or press it with Fn.

Method 3: Unmute in the app

Meeting apps have their own mute that works separately from Windows:

• Teams: select the microphone button in the meeting controls, or press Ctrl + Shift + M.
• Zoom: select Unmute at the bottom left, or press Alt + A. Holding the Space bar unmutes you temporarily.
• Google Meet: select the microphone button, or press Ctrl + D.
• Discord: select the microphone icon next to your name at the bottom left.

If the host muted everyone, you may need to ask to unmute.

Method 4: Check the Sound Control Panel

1. Press Windows key + R, type mmsys.cpl and press Enter.
2. Open the Recording tab, double-click your microphone and open Levels.
3. If the speaker icon next to the slider has a red circle, select it to unmute. Raise the level and select OK.

On the Recording tab, also make sure the microphone isn’t disabled: right-click an empty area, tick Show Disabled Devices, then right-click the mic and choose Enable.

Method 5: Check the hardware

• Headsets: many have a mute switch on the cable or a flip-up boom mic that mutes when raised.
• USB microphones: look for a mute button or a light that turns red when muted.
• Bluetooth: make sure the device is connected in Settings > Bluetooth & devices, and choose its Headset or Hands-Free option as the input.

Still can’t be heard?

1. Open Settings > Privacy & security > Microphone and turn on Microphone access, Let apps access your microphone and Let desktop apps access your microphone.
2. Choose the right microphone inside the app’s audio settings, not just in Windows.
3. Run the troubleshooter: Settings > System > Troubleshoot > Other troubleshooters > Recording Audio (or open the Get Help app and search for microphone).

Frequently asked questions

Why does my mic keep muting itself?

Some apps, including Teams and Zoom, can mute you when you join a meeting. Check the app’s audio settings for an option to join muted. A loose headset cable or a sensitive mute button can also be the cause.

Can I use my mic to type?

Yes. Press Windows key + H for voice typing. In Word, see how to dictate in Word.
