Audio crackling

[uzivkovic97]

Hello everyone. I have a problem with audio for a little bit over a month now. It's crackling all the time. I'm running Pop!Os Linux but I've tried running different Linux distros and Windows 10/11 as well so I'm positive it's not driver problem.
No matter where I plug my headphones in (back of the motherboard, front panel, monitor through HDMI), crackling is there.

I tried following: 2 different types of headphones, changed power strips, changed power outlet and I checked, it's grounded properly.

Crackling is more annoying when I plug headphones in the monitor than it is when I plug them on back of the motherboard or front panel. 

Does anyone have an idea of what I can try to fix this problem?
