To manually update the driver, go to your motherboard’s website (if you have no idea what motherboard you have, check this link) and download the latest version of Realtek audio driver.
If you don’t have the time or computer skills to update the driver manually, you can do it automatically with Driver Easy, which allows you to update a driver with just a few clicks.

2) Launch the application and click the Scan Now button to detect any problem drivers on your computer including the Realtek audio driver.

1) Right-click on the Start menu button and select Device Manager.
2) Click Action in the top and select Add legacy hardware.
3) Click Next.
4) Select the radio button next to Install the hardware that I manually select from a list (Advanced), and click Next.

TIP: If you see a yellow mark next to the driver, simply updating the driver can resolve the issue.
Method 3: Restore BIOS to default
The problem can be caused by the incorrect settings in BIOS. To fix the problem, you can try to restore BIOS to default. Regarding how to do it, you can refer to the below steps:
1) Enter BIOS.
For all laptops or desktops, entering BIOS starts with a reboot. After booting your computer, on the load screen, you should see a notification telling you what key you can press to access BIOS. Keep pressing that key to enter BIOS settings.
For most machines, it’s the F2 key but some laptops use DEL or F8 instead. If you have no idea what the key is, consult your computer manufacturer for the answer.
2) Once you’re in BIOS, you can press F9 or F5 to bring up the Load Optimized Defaults prompt. Or find the option under the Security tab or the Exit tab.
Information: The name of the option allowing you to restore BIOS varies depending on what motherboard you have. It could be Reset to Default, Load Factory Defaults, Load Setup Defaults, etc.
3) Use the arrow key to select Yes, then BIOS will be restored to default.
4) Once done, press the key next to Save and Exit.
5) Reboot your computer and check to see if the problem persists.
