And this is the way you use your Audiophile card? Does it
work OK under normal operating conditions (computer powered
up, inputs connected, etc.)?

My Lynx L22 card "farts" (actually it's more like a "silent
fart" kind of like a whistle) if I shut down the computer
with it patched to the monitors while they're still on. My
Hafler monitor amplifier "farts" when I shut its power down.
Been doing it for years. It doesn't affect anything.

I suspect that in your case, the "problem" is that the
computer power supply is leaving the output stage powered up
for a while after you turn off the computer and what you're
hearing is not unusual.
