Windows 10 playing sound while my laptop is locked

Hi guys,

My laptop is running with Windows 10 1809 version but suddenly So my PC just locked up. The sound is still coming through my laptop but I had absolutely no control over anything, it was all frozen. I was playing a game while I had one video playing on chrome.

Below is my laptop configuration:

   Intel i5 8th Gen with 4 core processor
   1 TB HDD
   8 GB RAM

This has been happening since last week. So, I try to uninstalled a few recent update but not helpful still I am facing the same issue while my get lock running any videos.

Thanks :grinning:


Hi @Fawell,

Patrick, the lock feature never stops the background tasks. It just locks the PC while the existing live tasks continue to run.

The lock feature just prevents other users to access the PC when you are away from the PC. It does not kill the ongoing live tasks and processes.

I understand the concern you have mentioned. Hence, I would suggest you to kindly close all open windows when you Lock the PC or you can even Log off the PC.
I would suggest you to kindly Mute the audio from Windows Sound Manager (Bottom-Right corner) to be sure the “Mute” function is applicable to all application.

You have mentioned 2 problem here first

  1. Locking the PC or Laptop doesn’t stop the audio or video running in your PC or Laptop. Because the lock feature just prevents you from unauthorized access from other users. It doesn’t kill the ongoing live tasks and processes running in your PC or laptop.

  2. You have mentioned your PC get freeze and you don’t have control on it. Please follow the below solution one by one and see anyone of them is helpful.

Run the SFC.

Follow the below steps:

  1. Open Command Prompt.
  2. Select “Run as Administrator”.
  3. Type “sfc /scannow” without quotes and hit Enter.
    Now check for the issue.

Run the DISM Tool.

If the issue persists, I would have you run the DISM tool to check the system health and will try to restore the files.

  1. Click on ‘Start’.
  2. Enter ‘Command prompt’ in the Search box.
  3. In the list of results, swipe down on or right-click Command prompt, and then tap or click ‘Run as administrator’.
  4. In the Administrator: Command Prompt window, type the following commands. Press the Enter key after each command:

DISM /Online /Cleanup-Image /CheckHealth
DISM /Online /Cleanup-Image /ScanHealth
DISM /Online /Cleanup-Image /RestoreHealth

To close the Administrator: Command Prompt window, type Exit, and then press Enter.

Note: The tool might take 15-20 minutes to finish running, so please do not cancel it.

Method 3:

Type the following in a Windows PowerShell as Administrator:

1.Launch PowerShell
2.Set-ExecutionPolicy Unrestricted
3.Get-AppXPackage -AllUsers | Foreach {Add-AppxPackage -DisableDevelopmentMode -Register “$($_.InstallLocation)\AppXManifest.xml”}

Restart your device.

I will suggest you two option.

  1. Reinstall the Audio driver
  2. Install the Audio driver from the manufacture not through Windows update or
  3. Reinstall the Windows 10 OS.

@AnthonyD is right, Lock screen doesn’t prevent the audio playing in your device. If you want to disabled playing audio file if your computer or laptop is locked please follow the below instruction and let us know if this was helpful.

  • Right click on each listed disabled audio device that you want to enable, click on

  • Enable and set it as default.

  • Click OK to close the Sound window.

Restart the computer and check the result.

If the above instruction was not helpful please follow the below instruction:

Check if any of the sound items in the device manager is disabled. If yes, then enable it. To do this, try these steps.

  • Go to Device manager.

  • Expand Sound, video and game controllers’ item.

  • Right click the sub sound items and click

  • Restart the computer and check the result.

I suggest you to run the hardware and sound troubleshooter
and check if it helps.

  • Type “Troubleshoot” without quotes in search and click on

  • Troubleshooting in the results displayed on the left side of the screen.

  • In the new window, click

  • Hardware and Sound.
