I can hear the radio playing in the background of my computer when I plug in my headphones and need help. When I am using my computer (XPS 9Q33) and plug in my headphones (sony studio mdr7506) I hear a very faint radio broadcast in the background. If I unplug the headphones or turn the volume off I no longer get the radio. Also, if I plug these headphones into other computers no radio interference comes up. Any suggestions would be great, thanks guys!
