Fix No Sound After Update on Windows 11
Lost all audio after a Windows 11 update? It is usually a switched output device or a rolled driver. Here is how to get sound back in minutes.
Nothing kills confidence in a Windows update like rebooting to total silence. The reassuring news is that "no sound after an update" almost never means broken speakers. It usually means the update switched your default output to a device that is not connected, or replaced a working audio driver with a generic one. Both are quick to reverse.
Quick answer
No sound after a Windows 11 update is usually caused by the default output device being switched to something not connected, a disabled Windows Audio service, or a corrupted audio driver. Fix it by selecting the correct output device under Sound settings, restarting the Windows Audio services, then updating or reinstalling the audio driver in Device Manager. Turning off audio enhancements resolves the remaining cases.
Key takeaways
- Updates often switch the default output to a monitor or virtual device; reselect your real one.
- The Windows Audio service can be left stopped after an update; restarting it restores sound.
- A corrupted or generic driver is a top cause; reinstalling lets Windows restore a working one.
- Audio enhancements can silence certain devices; disabling them is a reliable fix.
- The built-in audio troubleshooter resolves a fair share automatically.
Check the output device first
An update frequently changes the default playback device, so Windows sends sound to a disconnected HDMI monitor or a virtual device and your speakers sit silent. This is the most common cause and the fastest to fix.
- Right-click the speaker icon in the taskbar and choose Sound settings.
- Under Output, select your actual speakers or headphones, not a monitor or virtual device.
- Confirm the volume slider is above zero and the device is not muted.
- Play audio to test.
Restart the Windows Audio services
If the right device is selected but there is still silence, the audio service may have been left stopped after the update. Restarting it and its companion service brings sound back without a reboot.
- Press Win+R, type
services.msc, and press Enter. - Right-click Windows Audio and choose Restart.
- Right-click Windows Audio Endpoint Builder and choose Restart.
- Confirm both are set to start Automatically, then test audio.
Update or reinstall the audio driver
Updates sometimes replace a manufacturer driver with a generic Microsoft one, or leave the existing driver in a broken state. Reinstalling lets Windows restore a clean, working driver on the next boot.
In Device Manager, expand Sound, video and game controllers, right-click your audio device, and choose Update driver. If that does not help, choose Uninstall device instead and restart; Windows reinstalls a working audio driver automatically. For laptops, grabbing the audio driver directly from the maker's support page is more reliable than Windows Update.
Turn off audio enhancements
Audio enhancements are processing effects that occasionally produce silence on specific devices after an update. Disabling them is a quick, safe test.
Go to Settings, System, Sound, select your output device, open Audio enhancements, and set it to Off. Test playback again.
Match the symptom to the fix
| Symptom | Likely cause | Fix |
|---|---|---|
| Silence right after an update | Default output switched | Reselect your real device under Output |
| No audio and the icon shows an X | Windows Audio service stopped | Restart Windows Audio in services.msc |
| Sound worked, then went dead generically | Driver replaced with generic one | Reinstall the maker's audio driver |
| Silence on one device only | Audio enhancement conflict | Turn off audio enhancements for that device |
| HDMI monitor has sound but speakers do not | Wrong default device | Set speakers as the default output |
| No output device listed at all | Driver failed to load | Uninstall the device and reboot to reinstall |
What to do right now
Work through these in order and stop when sound returns:
- Reselect your real output device under Sound settings.
- Restart Windows Audio and Windows Audio Endpoint Builder in
services.msc. - Run the built-in audio troubleshooter.
- Update or reinstall the audio driver in Device Manager.
- Turn off audio enhancements for the affected device.

Frequently asked questions
Why did an update kill my sound?
Updates can switch the default playback device, stop the Windows Audio service, or replace your audio driver with a generic version. None of these damage the hardware; they change software state. Reselecting the output device and restarting the audio service reverses the most common cases.
Should I roll back the update?
Not as a first step. Reselecting the output device, restarting the audio services, and reinstalling the driver fix nearly all cases without rolling back. If none of that works and the problem clearly began with a specific update, you can uninstall that update from Windows Update history, but try the quicker fixes first.
The audio driver keeps reverting to a generic one. What do I do?
Windows Update sometimes reinstalls a generic driver over the maker's. Download the correct driver from your PC or sound card maker, install it, then pause driver delivery through Windows Update or set your device driver policy so Windows stops overwriting it.
Why does my HDMI monitor have sound but my speakers do not?
The update set the monitor as the default output. Right-click the speaker icon, open Sound settings, and choose your speakers or headphones under Output instead of the monitor. Windows will then route audio to the device you actually listen through.
