I haven't tried installing it on OneUI devices, but had a lot of troubles getting it to work on my Oneplus. This discussion has good instructions on how to get it working. I personally did not used it, as I tackled this problem before it was created, but most of the steps from this instruction I remember doing.
Just in case, have you tried enabling legacy mode in settings?

The issue with Viper on OneUI 4 is the installation of the driver, no combination of Audio compatibility magisk modules worked, no matter what you do Viper is never able to install the driver, meaning that you can't even access any settings in Viper because the driver install prompt pops up every time you open the app.

That's strange. Is Viper magisk module just not getting installed? Only thing I can suggest is to try to install it using Zackptg5 installer.

The magisk module installs but the driver doesn't. And the rootless installer can't really be used because there's no twrp available for the tab s8+. I tried an app which supposedly can flash the zip bit it didn't work

PowerAmp Equalizer can do the same without root

No it doesn't lol.

PowerAmp is just a basic eq with a compressor

I use Viper for DDC and Convoler mainly, equalizer secondarily
