Don't know if this is the right section in the forum to post this (sorry ). But I need some help from audiophiles and Apple experts. I have no knowledge about audio equipment so i hope someone is willing to help me out. Currently i have an airport express connected by 3.5mm audio cable to the line in of my speakers. My airport Express is hooked up to a ethernet cable, and transmits wifi signal to share my internet. When i turn up my speakers to 80% i can hear static noise (speaker interference). Is there something i can do about this?
