crackle only through monitors?

[davidc0]

hey guys im running a GIGABYTE GA-H270N-WIFI and through the guides it tells me to use ALC1220 and 100/200 Series Audio through multibeast, my headphones work fine though the port in the back of the computer, however my monitors get a constant crackle and background noise any idea?
