Computer systems, especially sound cards, but also serial ports, are
notorious for being built with "pin 1 problems." A connection to
earth is rarely a fix for RFI. Proper shield termination is.
See http://audiosystemsgroup.com/RFI-Ham.pdf
and http://audiosystemsgroup.com/Pin_1_Revisited.pdf

Pin 1 problems are also a major cause of hum and buzz in audio
systems.
