When my PC card passes traffic, the speakers in my laptop buzz. What is the problem?
A. This problem comes from inadequate shielding around the PCMCIA socket. The radio energy of the card that passes traffic leaks over into the speakers (because the energy is not sufficiently contained in the card socket) and manifests as a buzz in the speakers. Therefore, this buzz is not a problem with the card, but with the socket. Resolution must come from the laptop manufacturer that chose not to shield the socket.
