Sonic Studio 3 is not compatible with the VIII Formula SupremeFX sound chipset.
I never used Sonic Studio 2 after the upgrade and had no installation problems on Windows 10 Pro v1803, OS Build 17134.228.
Driver before installation (Device Manager/ Sound, video and game controllers/Realtek High Definition Audio):
Downloaded (right clicked and unblocked file) and extracted file (Realtek_AudioDriver_Win7-10_V6018158_20170607) to new folder, selected AsusSetup it does not matter if run as administrator or just double click.
Then I got this warning followed by a quick flash of a small gray box with letters and it then disappeared (no restart required, but I restarted anyway, because SupremeFX was stopped during installation and did not open when I plugged in the headset or microphone):
Driver after installation (Device Manager/ Sound, video and game controllers/Realtek High Definition Audio):
EQ Functions and Microphone work. Tested microphone using Windows Settings/Privacy/ Microphone –off, microphone not working. Turned back on and microphone works.
I did experience the loop of installing and uninstalling with Windows 10 Pro V1709. Once the program uninstalled the driver, I restarted and when it installed the driver, I did not restart the computer. I think I ended the process in Task Manager, rebooted and Sonic Studio 2 worked.
Anyway, I never installed Sonic Studio 2 and Sonic Radar 2 until now, just to see if it worked.
