Hi,
This issue might occur if the audio drive is corrupt or not working properly.
I would suggest you to uninstall the audio driver and then scan for hardware changes that will reinstall the driver for the audio card. Follow the methods listed below:
Method 1:
Follow the steps to uninstall the Realtek audio driver and then reinstall the driver:
- Press Windows+R keys and type “devmgmt.msc”.
- Expand the Sound, game and video controllers. Right Click on the audio driver and select Uninstall.
- Click on Scan for hardware changes icon on the top of the window. Check if it fixes the issue. If not, restart the laptop and the device drivers will be reinstalled automatically.
If the issue still persists, proceed to the next method.
