Hi! @Rabby2,


In Device Manager, expand Sound, Video and Game Controllers.  Right-click the Realtek device and select disable and again right click and enable the driver and restart the PC, check if you still have issues.


Try updating the BIOS and audio drivers on the PC to the latest version.


Update the BIOS using this link. Click Here


Update the audio drivers using this link. Click Here


Also, if you still have issues please try the steps recommended below.


Go to Control Panel -> Devices Manager -> Audio, Video and Games Controllers

And find there Realtek audio card. Click on it with the right button of your mouse and choose ' Properties '.
Select ' Driver ' tab and select Roll Back Driver check if the issue persists.


Let me know if this works!

Have a great day! 🙂
