I used to have a static problem when i turned my audio interface (focusrite 2i2) volume up so i purchased a power distribution system and that eliminated all the hum. i recently purchased a m-audio sub to match my bx-5's and that is when the annoying "alien" like noise started occuring when i play games (CS:GO) the noise only persists when i enter a match online. i am routing the cables from my interface to sub, then from the sub out to my monitors (i believe this is called crossing over). i saw other threads saying its an interference problem with the motherboard or something like that but i am ruling that out because the problem only started happening after i started using the sub. does anyone have any tips or solutions? my pc is plugged into a wall socket and everything else is plugged into my power distributor.
