I am having issues with the Sonic Studio 3 as well not working properly on my Maximus X Hero WI-FI AC. I have uninstalled / reinstalled the Sonic Studio III with the Supreme FX multiple times already. I have reinstalled with both disc and from ASUS site for the newest version Ava.
I run my system through optical only through my stereo.
I also had several issues with the SonicStudioIII, after installation, it starts SSIII but it won't starts csgo.exe (but no error msg, it just didn't start probrbly ) at the end I deinstalled the SonicStudioIII and replaced with the NahimicIII from the WindowsStore.
It has less featueres, such as "Device Routing" but it has all the Soundboost. So maybe you will be happy with it as well... here is the link to the windows store:

I had an issue where the EQ wasn'tworking in Sonic suite. The fix for me was on windows 11, go into sound settings, the device you are using and make sure "Audio enchancements" is set to "Device Default Effects". You're welcome 🙂
