Solved! Buzz noise on external audio card

[Toshka_31]

Hi all!
I have a M-Audio 192 4 audio card connected with USB (no external power supply) and Audio-Technica ATH-M40X headphones. And when i launch any game i hear buzz noise. But i dont hear it on the studio monitors.
What can be the reason? Please help me

Cold be a bad connection on it, test it with another set of headphones/earbuds. Are you using any adapters or extra cables?
