I see. Yes, Windows reinstall the default. If you haven't tried the Realtek audio driver provided on the laptop manufacturer's website, please try that. If you already try it and the issue still persists, you can either contact the laptop manufacturer's support so they can assess the situation or get in touch with a Microsoft agent so they can remotely access your laptop to check. You can use this form to create the support ticket.
