Number 2 is untypical. Using headphones or external speakers,
even an external (and distant) amplifier with speakers leads
to the same observation.
As it has mentioned before, this seems to be an effect of
interferences either in the area of the connection cables
or within the computer (AF signal processing and amplification
gets interference signals from keyboard / mouse connections).

But not if the problem is within the computer (read: the mainboard
and the expansion cards).

Or the use of home-made shielded cables. :-)
