Turn down the amplifier on the card, use as short a cable to your speakers
as you can manage, and do as much of the amplification as is practical
with the amp in your speakers (or otherwise with an amp outside your case).

I got the same effect on a 10 MHz XT clone and an original Sound Blaster,
with my headphones--which had a 6', unshielded cord. I could hear disk
accesses and video I/O quite distinctively...
