Hello, I did what you said, and again I lowered the audio driver and I could install without problems each one of what I needed, I will explain here the steps.
1) I downloaded the AUDIO Version 22.214.171.12446 2019/12/03 driver from the asus page of that model: ROG STRIX Z370-G GAMING (WI-FI AC) To decompress it, since it weighs 686.47 MBytes because it contains inside SonicRadar and SonicSuite installers.
2) After installing the AUDIO driver, it may take a while (seconds) at the end of the installation and tell you that such hardware is not bearable. (Audio is installed correctly, but the warning is by SonicRadar and SonicSuite)
There are cases that run all run since it is bearable, so no problem.
In the case that the first thing that is not supported happens, you have to go to the SonicSuite folder and run the Setup_FineTuningTool2, after that, you must run Setup_SonicRadar3 or Setup_SonicStudio3 (no matter the order)
