In game buzzing

[NFSU]

hello everyone,

I have encountered strange problem. Whenever i launch games my headphones start to buzz. This annoying noise makes playing any games highly unpleasureable. Interestingly, this happens only in some games (CS:GO, DOTA2, PUBG) and the buzzing changes tone whenever i change video settings. Because of that i assume its probably not electromagnetic interference. Maybe its because of game engine? I don't have any other source 2/ unreal 4 games to check this theory. In addition i don't recall dota2 making this kind of annoying sounds previously, i really dont have idea what might be the problem. If, however, it was the case of interferences maybe some kind of DAC far from PC could solve the problem? I'm not an expert in that matter and I've read simillar posts on tomshardware and one here at ltt. Haven't found any working solution(I've seen people talking about removing grounding cables from speakers or turning VSYNC off, didn't help me).

Any help will be appreciated.
