If sound is not working after a Windows 11 update, your primary audio device may have been muted or swapped during the installation. You can resolve this issue by selecting your correct output device in Quick Settings, running the automated audio troubleshooter, or reconnecting your Bluetooth audio hardware. Follow these step-by-step methods to restore sound on your PC.
When your sound is not working after a Windows 11 update, the problem typically stems from altered playback defaults or disrupted audio device connections caused by system changes during reboot. This frustrating issue affects users across Windows 11 24H2, Windows 11 25H2, and Windows 11 26H1, leaving built-in speakers, wired headphones, or Bluetooth headsets entirely silent.
In most cases, the update process temporarily resets your audio hardware configuration or points audio output toward a different display or virtual channel. By following the targeted troubleshooting methods below, you can quickly locate where the signal path was broken and restore sound to your speakers or headphones.
Method 1: Check your sound output device and volume levels
Use this quick method first if your PC lost sound immediately after installing a new Windows update. Windows updates frequently reassign the default sound output to an external monitor or secondary display driver.
- Click the Sound icon (shaped like a speaker) located on the right side of your taskbar next to the clock.
- Look at the volume slider on the Quick Settings menu to confirm that the volume is turned up and that the speaker icon next to the slider is not muted.
- Click the Select a sound output icon (the arrow pointing right next to the volume bar).
- The screen will show a list of playback devices under the Sound output heading; click your primary speakers or audio headset to select it.
After selecting your main audio output device, play any media file or system sound to verify that audio playback has been restored.
Method 2: Run the audio troubleshooter in the Get Help app
If selecting your playback device manually does not fix the problem, use this method to trigger built-in automated diagnostics. Windows 11 includes dedicated troubleshooting tools designed to fix system services and sound drivers.
- Click the Start button on your taskbar and select the Settings app (the gear icon).
- On the System tab in the left sidebar, click Troubleshoot on the main right-hand pane.
- Click Other troubleshooters on the screen.
- Locate the Audio listing and click the Run button next to it.
- The system will launch the Get Help app; follow the on-screen prompts to allow automated diagnostics to check your sound configuration.
Once the scan finishes, the Get Help app will inform you of any detected issues and automatically apply fixes to restore sound functionality.
Method 3: Reconnect Bluetooth audio devices
Use this method if your sound issue is specific to wireless headphones, earbuds, or external Bluetooth speakers. System updates can occasionally disrupt saved pairing keys and connection profiles for Bluetooth devices.
- Click the Start menu button and select Settings.
- Click Bluetooth & devices from the left navigation panel.
- Look under the Devices section on the screen to check if your wireless headphones or speakers display as Connected.
- If the device is stuck or not outputting sound, click the three-dot menu icon next to your Bluetooth device and select Remove device.
- Click the Add device button near the top of the screen, select Bluetooth, place your audio device into pairing mode, and click its name when it appears on the screen.
Once re-paired, Windows 11 will recreate the Bluetooth audio path and send sound directly to your headset.
Method 4: Check for system repair updates in Windows Update
If basic audio troubleshooting does not restore sound, use this method to check for additional system fixes or driver patches queued in Windows Update.
- Click the Start button and open Settings.
- Select Windows Update from the bottom of the left menu pane.
- Click the Check for updates button at the top right of the screen.
- If repair updates or driver components are listed, click Download & install.
- Restart your computer if prompted after installation completes.
Before allowing your computer to restart, ensure all open documents and files are saved to prevent data loss. Once your computer restarts, check your volume control to confirm sound is working.
If nothing worked
If none of these troubleshooting methods restored your audio, launch the Get Help app directly from your Start menu for additional automated support options, or open the Feedback Hub app to report the audio failure directly to engineers. You can also visit the official Windows release health page online to review active safeguards and documented update issues that may affect audio performance on your specific build.
