How to Fix Windows 11 Sound Not Working After Update

If your sound stopped working immediately after a Windows 11 update, the issue is usually caused by audio driver conflicts, incorrect sound settings, or glitches from the update itself. Start by checking your sound settings and hardware connections, then update or roll back your audio drivers if needed. Running Windows’ built-in audio troubleshooters and verifying audio services can also help restore sound.

Why did my sound stop working after the Windows 11 update?

After a Windows 11 update, your sound may stop working because the update installs new system files or drivers that conflict with your existing audio setup. The most common cause is an incompatible or corrupted audio driver. Updates can also reset sound settings, muting devices or changing the default playback device without notifying you. In some cases, a bug in the update temporarily disrupts audio until a patch is released or the system stabilizes.

Have you checked your sound settings and hardware connections?

Before trying advanced fixes, confirm that basic settings and connections are correct. Check that your volume isn’t muted or too low by clicking the speaker icon on the taskbar and adjusting the slider. Verify the correct output device is selected, since updates can switch to inactive devices. To do this, click the speaker icon and choose the proper audio device from the list. Inspect your speakers or headphones to ensure they’re plugged in securely and powered on. For Bluetooth devices, confirm they are connected. Disconnect and reconnect your audio devices to rule out loose connections or hardware recognition issues.

How to update or roll back your audio drivers to fix sound problems

Audio driver problems after updates are common and can often be fixed by updating or rolling back drivers.

1. Right-click the Start button and select Device Manager.

Device Manager

2. Expand the "Sound, video and game controllers" section.
3. Find your audio device (for example, "Realtek High Definition Audio" or "Intel Display Audio"), right-click it, and choose "Update driver."

4. Select "Search automatically for updated driver software." If Windows finds a newer driver, it will install it.

If updating doesn’t restore sound, try rolling back to the previous driver:

5. Right-click the audio device again and choose "Properties."
6. Go to the "Driver" tab and click "Roll Back Driver" if available.

Driver tab > Roll Back Driver

If neither updating nor rolling back works, uninstalling and reinstalling the driver can help:

7. Right-click the audio device and select "Uninstall device," then restart your PC. Windows will reinstall the driver automatically.

How to run Windows built-in audio troubleshooters and check services

Windows 11 has troubleshooting tools that can find and fix common audio issues.

1. Open Settings and go to System > Troubleshoot > Other troubleshooters.

Settings path: System > Troubleshoot > Other troubleshooters

2. Find "Playing Audio" and click "Run."
3. Follow the prompts to let Windows diagnose and fix audio problems.

If this does not resolve the issue, check that essential audio services are running:

4. Press Windows + R, type services.msc, and press Enter.

services.msc

5. Locate "Windows Audio" and "Windows Audio Endpoint Builder."
6. For each service, right-click and select "Restart." If a service is stopped, right-click and select "Start."

These services are necessary for audio to work. If restarting them doesn’t help, the problem may be deeper in the system or with the drivers.

How to test if your sound is working again

After trying fixes, confirm your sound is restored:

1. Click the speaker icon on the taskbar and select "Open volume mixer." Play audio (such as a YouTube video or music app) and see if the volume bars move.
2. In Settings, go to System > Sound > Output, select your audio device, and click "Test." You should hear a test tone.

Settings path: System > Sound > Output

3. Open Device Manager, expand "Sound, video and game controllers," and check that your audio device shows without warning symbols like yellow exclamation marks.

If the test tone plays and the device status is normal, your sound should be working.

How to avoid sound problems after future Windows updates

To reduce the chance of sound issues from future updates, take these steps:

• Create a system restore point before installing updates. This allows you to revert your system if problems occur.
• Back up your current audio drivers by exporting them using third-party tools or from Device Manager.
• Wait a day or two after updates before installing them to see if others report sound issues.
• Regularly check your audio hardware manufacturer's website for updated drivers, which may be more reliable than those Windows installs by default.

These steps won't guarantee you avoid sound problems, but they make it easier to recover if they happen.

Conclusion

If none of these steps restore sound, check Microsoft’s support forums or the Windows Update history page for known issues with the update you installed. You might need to uninstall that update temporarily until a fix is available. As a last resort, restoring your system to a point before the update can resolve the problem. Keeping your drivers updated and monitoring your system after updates helps prevent recurring sound issues.
