You need Realtek Audio Drivers (UAD - ASUS ROG SS3-DTS MB) from the first post of this thread : [DRIVERS] Realtek Audio (MB | Intel 2xx/3xx/4xx/5xx/6xx & AMD 3xx/4xx/5xx).
Follow scrupulously your CLEANUP process then your INSTALL process, for the next drivers packages that I would release, you will can directly follow your UPDATE process.
Since you have an ASUS ROG SS3|DTS Sound Unbound motherboard, the configuration of the Upmix / Surround must be done via Sonic Studio III (SS3) and/or DTS Sound Unbound :SS3 : Sonic Studio > Basic Mode :Sonic Studio Effects : On
Upmix / Surround : Checked
DTS Sound Unbound : DTS Headphone:X > Enable DTS Headphone:X > Configure > Click on the 3 dots (...) and type the reference of your audio equipment :- If you find your audio equipment select it.
- If you don't find your audio equipment :If you use earphones : Choose the earphones icon
If you use headphone/headset : Choose the headset icon

For my part I have an ASUS ROG SS3 motherboard, and I additionally bought DTS Sound Unbound with the aim of using DTS Headphone:X spatialization when the games are compatible in addition to SS3 spatialization, and to use SS3 spatialization (Music global profile (untouched/default) + Upmix / Surround checked) for all other content including games that do not are not compatible with DTS Headphone:X spatialization.
