How to Fix No Sound After Windows 11 Update

You just installed the latest Windows 11 update, but now your PC is completely silent. Your speakers or headphones are plugged in, the volume looks fine, but there’s still no sound. Don’t worry — this is one of the most common issues after a major Windows update.

Sound problems often occur because updates can reset drivers, change the default audio output, or disable your sound enhancements. In this guide, we’ll show you how to fix no sound after a Windows 11 update step-by-step — from checking your sound settings to reinstalling audio drivers.

Fix No Sound After Windows 11 Update

You’ll need administrator access to your Windows 11 PC and an internet connection (for driver updates).

Tip: If you’re using external speakers, headphones, or Bluetooth devices, keep them connected during troubleshooting so you can verify fixes as you go.

Step 1: Check Physical Connections and Volume

Before diving into software fixes, make sure it’s not something simple.

1. Verify that your speakers or headphones are securely plugged in.
2. If you’re using Bluetooth, open Settings → Bluetooth & devices and confirm the device is connected.
3. Check that the Volume Mixer isn’t muted:
   • Right-click the speaker icon on the taskbar.
   • Select Open Volume Mixer.
   • Make sure your output device and app volumes are turned up.

Sometimes Windows changes the active output device after updates, so even if your system volume looks fine, sound might be going to the wrong device.

Step 2: Select the Correct Output Device

Windows updates can switch your default playback device automatically — for example, from “Speakers (Realtek Audio)” to “Digital Output.”

To fix it:

1. Click the sound icon on the taskbar.
2. Next to the volume slider, click the arrow (˅) to open the output device list.
3. Select the correct playback device (for most users, it’s Speakers or Headphones).

Alternatively, go to Settings → System → Sound, and under Output, select your preferred device.

If the correct device isn’t listed, continue to the next step — the driver might need reinstalling.

Step 3: Run the Audio Troubleshooter

Windows 11 has a built-in troubleshooter that automatically detects and fixes common sound problems.

1. Press Windows + I to open Settings.
2. Go to System → Troubleshoot → Other troubleshooters.
3. Find Playing Audio and click Run.
4. Follow the on-screen steps and select your device when prompted.

If the troubleshooter finds and fixes something, restart your PC and test the sound again.

Step 4: Restart Windows Audio Services

Sometimes updates can stop or disable key audio services. Restarting them can restore sound instantly.

1. Press Windows + R, type services.msc, and press Enter.
2. In the list, find these services:
   • Windows Audio
   • Windows Audio Endpoint Builder
   • Remote Procedure Call (RPC)
3. Right-click each one and select Restart.
4. Double-click Windows Audio, make sure Startup type is set to Automatic, then click Apply and OK.

Once done, reboot your system and test again.

Step 5: Update or Reinstall Your Audio Drivers

Driver conflicts are the most common cause of sound loss after Windows updates. Updating or reinstalling the driver often resolves the issue.

Update via Device Manager:

1. Press Windows + X and choose Device Manager.
2. Expand Sound, video and game controllers.
3. Right-click your audio device (e.g., Realtek High Definition Audio) and select Update driver.
4. Choose Search automatically for drivers.

If Windows says the best driver is already installed, try reinstalling it manually.

Reinstall Audio Driver:

1. Right-click the audio device again and select Uninstall device.
2. Check Attempt to remove the driver for this device, then click Uninstall.
3. Restart your PC — Windows will reinstall the correct driver automatically.

If it doesn’t, visit your PC or motherboard manufacturer’s website (for example, Dell, ASUS, HP, Lenovo) and download the latest Windows 11 audio driver for your model.

Step 6: Roll Back the Audio Driver (If Sound Stopped After Update)

Sometimes Windows installs a newer but incompatible driver version. You can roll back to the previous version.

1. Open Device Manager again.
2. Right-click your audio device → Properties.
3. Go to the Driver tab.
4. Click Roll Back Driver (if available) and follow the prompts.

After rolling back, restart your system and check if sound returns.

Step 7: Disable Audio Enhancements and Spatial Sound

Windows sound enhancements can sometimes conflict with driver updates.

1. Right-click the speaker icon on the taskbar and select Sound settings.
2. Scroll down to Advanced → All sound devices.
3. Select your playback device.
4. Under Output settings, toggle Enhance audio off.
5. Also set Spatial sound to Off.

Then restart your PC and test audio playback again.

Step 8: Reset Sound Settings

If nothing works so far, reset all sound configurations to their default state.

1. Open Settings → System → Sound.
2. Scroll down and click More sound settings.
3. In the Playback tab, select your default device and click Properties.
4. Under the Advanced tab, click Restore Defaults.

Alternatively, type Sound in the Start menu, open Sound Control Panel, and reset settings from there.

Restart your system afterward to apply the changes.

Step 9: Check for Optional Updates (Driver Fixes)

Windows sometimes releases post-update patches to fix sound problems.

1. Open Settings → Windows Update → Advanced options.
2. Click Optional updates.
3. Look under Driver updates for any Realtek, Intel, or HD Audio drivers.
4. Install any available updates and restart your PC.

This often resolves issues introduced by earlier patches.

Step 10: Run System File Checker (SFC) and DISM

Corrupted system files can interfere with driver communication. Use SFC and DISM to repair them.

1. Press Windows + X → Windows Terminal (Admin).
2. Run these commands one by one: sfc /scannow DISM /Online /Cleanup-Image /RestoreHealth
3. Wait for the process to complete, then restart your computer.

After rebooting, test sound again.

Step 11: Restore Your System (If All Else Fails)

If the sound issue started right after the 25H2 update (or any major patch), restoring to a point before the update can fix it.

1. Press Windows + R, type rstrui, and press Enter.
2. Click Next, select a restore point from before the sound stopped working, and follow the prompts.
3. After restoration, Windows will restart, and your sound should return.

You can then reinstall updates carefully, checking audio after each one.

Step 12: Reinstall the Windows Update (Last Resort)

If no method works, the update installation itself may have been corrupted.

1. Open Settings → Windows Update → Update history → Uninstall updates.
2. Remove the latest cumulative update.
3. Restart your PC and verify sound.
4. Reinstall the update through Windows Update or using the Windows 11 Installation Assistant.

This refreshes system files without deleting personal data.

Wrapping Up

Losing sound after a Windows 11 update can be frustrating, but it’s rarely permanent. Start with basic checks — like selecting the right output device and running the troubleshooter — before moving on to reinstalling or rolling back drivers.

Most users regain audio by updating drivers or restarting the Windows Audio service. For deeper cases, running SFC/DISM or performing a system restore usually does the trick.

Once resolved, your sound should be back to normal — and you can enjoy your updated Windows 11 system without missing a beat.
