USB Audio Stutter Issue

Hi,

MB: Asus Z170-A

CPU: Intel 6600k

Installed with UniBeast

OS version: Mojave 10.14.5 18F132

I'm new to Hackintosh but have managed to get everything working, apart from a constant stuttering when running audio over USB (Focusrite Scarlett 2i2). It sounds like a clock issue but I can't seem to fix it.

Things I've tried: - Different USB ports (2.0 and 3.0) - Different USB cable - Manually adding a busratio argument to the Boot section in Clover - Manually setting the CPU frequency and bus speed in Clover - Changing the clock speed of the 2i2 from Audi/MIDI settings - Enabling USB HighCurrent in Clover - Same results in High Sierra

Would appreciate any suggestions on how to fix this!
