Sonic Radar helps you detect enemies but in some cases has been known to be detected as a cheat and could possibly get you banned so I don't use it.
Sonic Studio is nice to have as you can adjust the effects and adjust the equalizer for your own personal sound preference.
What I'd try is uninstalling the Realtek driver, run CCleaner to clean the registry then install the latest Realtek driver that supports sonic radar and sonic studio.
Try version 126.96.36.19939
You just have to pick up your UAD drivers here, and all the rest will update automatically.
The drivers that are on the link that propose Nate152 are HDA drivers (traditional), the drivers that I propose are UAD drivers (new generation), one like the other are compatible Z270. If you are on Windows 10 64 bit 1709 or more recent I advise you to install UAD (new generation) by following the instructions of the first post of this thread.
