Hi,
Looks to be the same driver. I'm in the UK so when I search I get the UK site for Asus.
Do you have all their drivers especially the Chipset driver?
Do you know if there is a way the Audio hardware could have been turned off in the bios. I wouldn't think it has but it's just a thought.
There is the option to repair/carry out an in-place upgrade of Windows 10, if you wish.

essentially download the latest ISO image file. (if you do not have it already) Mount the ISO in File Explorer, select the new drive letter then run setup. It will take you through the repair and should allow all files, apps and programs to be retained.
