I've fixed all my BIOS settings, set Cpu bus ratios and nothing has worked. I've tried changing SMBios. Basically any audio with crackle really bad but as soon as I move my mouse it will stop. I'm on MacOS High Sierra 10.13.6

Exactly the same sound problem on High Sierra and Mojave, quickly move mouse and sound becomes normal, stop moving and problems reappear.
I assume that problem occurs due to a drop cpu frequency, but I haven't yet found a solution.
This sound problem is everywhere: built-in audio, hdmi, usb sound card.
Used hardware in signature.

Anyone found a solution for this? I'm using very similar hardware to @Programmer. And the issue is in Mojave, too.
Set overclock to an even number. Many users have found this fixes it. I run a 4.00GHz OC and no issues.
