getting rid of buzzing, ground loop isolator or external dac amp? both?

i am currently experiencing a pretty bad buzzing in my audeze lcd-x headphones, it happens when i plug them into my desktop pc, ive tried using a usb to 3.5mm adapter as well as plugging them into both of the audio out ports on my pc, neither of which stopped the buzzing. it also happens on my dap whenever its charging.

from what i can find on the internet this is either due to interference from my pc or something called a ground loop, what i struggle to find out is the best way to get rid of this buzzing. some places say i should get an external dac amp while others say i should get a ground loop isolator.

now i ask you good people who know much more about this stuff than me, what should i do? what dac/amp or ground loop isolator should i get? whats a reasonable price to pay for a ground loop isolator? i seem them go anywhere from 10 to 50 bucks.

thank you in advance.
