Fix Teams Speaker Audio Is Silent on Windows 11

When you join a Teams meeting on Windows 11 and hear nothing from your speakers, the cause is usually a wrong output device, a muted app volume, or a driver conflict. Teams can silently route audio to a device you are not using, such as a monitor or a headset that is turned off. This article explains the root causes and gives you a step-by-step fix to restore speaker audio in Teams on Windows 11.

You will learn how to check the Teams device settings, adjust Windows sound mixer levels, and update or reinstall your audio drivers. The steps apply to both the classic Teams desktop app and the new Teams app. If your speakers work in other apps but not in Teams, the fix is usually quick.

Why Teams Speaker Audio Goes Silent on Windows 11

The most common reason for silent speaker audio in Teams is that Teams is sending audio to a device that is not your active speaker. Windows 11 lets each app choose its own output device. If you previously used a headset or a USB speaker, Teams may still be set to that device even after you unplug it.

Another cause is the Windows sound mixer. Each app has an independent volume slider. If you muted Teams by accident or the slider dropped to zero, you hear nothing even though Windows volume is normal. This happens often when you press the mute key on your keyboard or use the volume flyout.

A third cause is a driver problem. Windows 11 updates can install a generic audio driver that does not work well with your sound card. Teams uses the Windows audio endpoint, so any driver issue affects Teams. Sometimes the driver is fine, but the audio endpoint is disabled in Device Manager.

Finally, Teams itself has a device settings page. If the speaker dropdown is set to “Default” but your default device changed, Teams may pick the wrong one. You can fix this by explicitly selecting your speaker in Teams.

Steps to Diagnose and Fix Teams Speaker Audio on Windows 11

Follow these steps in order. Test your audio after each step to avoid unnecessary changes.

1. Check the Teams speaker output device
   Open Teams and click your profile picture at the top right. Select Settings then Devices. Under Speaker, choose your actual speaker from the dropdown. If you are using built-in laptop speakers, pick the option that says Speakers or Realtek. If you use external speakers, pick the USB or Bluetooth device name. Click Make a test call to confirm audio.
2. Set the speaker as the default device in Windows
   Press Win + I to open Settings. Go to System > Sound. Under Output, select your speaker. Click Volume and make sure it is above 50. Then click More sound settings at the bottom. In the Playback tab, right-click your speaker and choose Set as Default Device. Click OK.
3. Raise the Teams volume in the Windows sound mixer
   Right-click the speaker icon in the system tray and select Open Volume Mixer. Look for the Teams icon. If the slider is at the bottom, drag it up to at least 50. Also check that the speaker icon under Teams is not crossed out. If it is, click it to unmute. Test audio again.
4. Restart the Windows audio service
   Press Win + R, type services.msc, and press Enter. Scroll to Windows Audio. Right-click it and select Restart. Do the same for Windows Audio Endpoint Builder. This resets all audio endpoints and often fixes silent audio.
5. Update or reinstall the audio driver
   Right-click the Start button and select Device Manager. Expand Sound, video and game controllers. Right-click your audio device and choose Update driver. Select Search automatically for drivers. If Windows finds no update, right-click the device and choose Uninstall device. Check the box that says Delete the driver software for this device and click Uninstall. Restart your PC. Windows will reinstall the driver automatically.
6. Run the Windows audio troubleshooter
   Open Settings with Win + I. Go to System > Troubleshoot > Other troubleshooters. Click Run next to Audio. Follow the prompts. The troubleshooter can detect muted apps and disabled devices.

If Teams Still Has No Speaker Audio After the Main Fix

Teams Shows a Muted Speaker Icon Even Though You Are Not Muted

This usually happens when Teams is using a different communication device. Open Teams Settings > Devices and check the Microphone dropdown. If the mic is set to a device that is also your speaker, Windows may apply a mute to that endpoint. Set the mic to a different device or to your headset. Then set the speaker to your external speakers.

Audio Works in Other Apps But Not in Teams

This points to a per-app setting in Teams. Close Teams completely. Right-click the Teams icon in the system tray and select Quit. Then reopen Teams. If the issue persists, go to Teams Settings > Devices and click Reset to restore default device settings. This clears any cached device selection.

Teams Is Silent Only in Meetings, Not in Calls

Meeting audio uses the same output as calls, but the meeting organizer may have set a specific device. Ask the organizer to check meeting options. Also check if you have multiple audio devices and the meeting is using the wrong one. You can change the speaker during a meeting by clicking the speaker icon in the meeting controls and choosing your speaker.

Bluetooth Speaker Connects But Teams Is Silent

Bluetooth speakers often have two profiles: one for music and one for calls. Teams uses the call profile, which may be set to a lower quality. In Windows Settings > System > Sound, click your Bluetooth speaker and disable the Hands-Free Telephony option if it is enabled. This forces Teams to use the high-quality profile.

Teams Desktop vs Teams on the Web: Audio Settings Comparison

Item	Teams Desktop App	Teams on the Web
Device selection	Full control in Settings > Devices	Uses browser default output device
Per-app volume	Controlled by Windows Volume Mixer	Controlled by browser tab volume
Test call	Built-in test call feature	No test call, must join a meeting
Driver conflicts	Can be affected by audio drivers	Less affected, uses browser audio stack

Use the desktop app for more control over audio devices. If the desktop app is silent, try the web version to see if the problem is app-specific.

Conclusion

You can now fix silent speaker audio in Teams on Windows 11 by checking the Teams device settings, adjusting the Windows sound mixer, and updating your audio driver. Start with the Teams speaker dropdown and the Volume Mixer because they solve most cases. If the issue remains, restart the Windows Audio service and reinstall the driver. For Bluetooth speakers, disable Hands-Free Telephony to force the high-quality profile. Use the test call feature in Teams to verify your fix before joining an important meeting.
