Literally.
Feedback? That is an open microphone somewhere, typically the one on the laptop itself. Can you disable it in the BIOS? Or perhaps it is the radio eavesdropping device implanted in your house by FBI agents back during the J. Edgar Hoover era. :-) If your problem is actually bleedthrough from some other source, then sometimes cleaning the connectors so they make good contact is helpful. Sometimes Oregon dampness corrodes connectors, and the corrosion acts like a diode, which rectifies radio signals, which makes the diode and audio system behave like a crystal radio receiver for AM signals. Or perhaps you need somebody to come take a look. This kind of thing is difficult to diagnose remotely.
