Thank you.
Can you go back to Device Manager > Video, audio and game controller. uninstall any of the Realtek audio related item.
If restarting t he computer doesn't help, go to this Intel page: https://www.intel.com/content/www/us/en/downloa...
Run the auto detect, and see if it recommends the Realtek audio to install. If so, install it and see if it makes any difference.
