Hi
@baysideYou are using 64-bit version of Windows 10, its not the audio driver causing the problem its the malfunctioning audio card causing the problem. Let's reset the BIOS settings to its factory default settings and try reinstalling audio driver again and if it fails to install again then you have no choice but to contact the Asus technical service.
Restart your laptop and soon as it powers back on press
F12 key during the post.
Use the directional keys
to select
Save & Exit tab, select
Restore Defaults option and press Enter key. After resetting the BIOS to its factory default settings save the changes and exit BIOS.
Try installing the audio driver again also try installing below driver if both fails to install then you will have to contact Asus technical service.
