Hi,
Here is a link to the latest version Asus drivers for Win10.
Find the ''Audio drivers'' appropriate to your laptop's audio controller, (Realtek, Conexant or Via), download and install.
Read the '''Notes''' near the top of the page as to how to install the drivers.

Do not be tempted to install drivers for other hardware in your laptop at this stage. Fix one problem at a time. If it ain't broke don't fix it.
