Well... finally I think I found the the fix for the no sound after OS reset. It is not Asus fix but something I found it by experimenting with the problem.
Here are my detailed steps of what I did.
a. OS reset
b. After OS reset and initial setup, here is the condition of the UX581-XB74T
No sound or output/input device
(MyAsus Software Update does not help)
c. Run Windows Update
Enabled "Receive update for other Microsoft..." in Advanced options and run Windows update again
d. Downloaded Intel iSST v10.23.0.2672 from MyAsus
and extracted files to its default folder
e. Search "Intel Media 2020" in Microsoft Update Catalog and downloaded Intel Media v 10.25.0.4040
Extracted .cab file to Intel Media 10.25.0.4040 folder with 7 zip
copied "Install.cmd and pnputil.exe from SmartSound_DCH_Intel_W10_64_v102302672 14077 folder
and pasted the into Intel Media 10.25.0.4040 folder
f. Uninstalled Device Intel SST OED and Audio Controller from Device Manager
(just in case it asked you to reboot the computer, DON'T reboot it)
g. Run Install.cmd in PowerShell from Intel Media 10.25.0.4040
h. Reboot the computer
You will notice that there is still no sound after reboot
i. Uninstall Intel SST OED from Device Manager
j. Update Intel SST Audio Controller to v 10.25.0.4040 from folder Intel Media 10.25.0.4040 in Download folder with "Have Disk" option
You will get "Update Driver Warning" but accept it by clicking "Yes"
Driver for Intel SST Audio Controller will updated to v.10.25.0.4040 and will also add Intel SST OED back
k. Now, update driver for Intel SST OED from Intel Media 10.25.0.4040 folder located in Download folder with "Have Disk" option
You might get the "Update Driver Warning" again so accept it by clicking "Yes" and the driver will be installed successfully
You will notice that the Intel SST OED Driver was installed successfully to v 10.25.4040.217 and the driver warning beside Intel SST OED will be gone and what is the most important the YOU HAVE YOUR SOUND BACK without any errors.
Result: Sound is back without any errors
That's all folks
