That sounds like the easiest solution. Perhaps you were too ahead of your time.
I'm going to wait and see what responses you get this time.

Thank you Tim:
If you don't mind, I'll post a summary of this solution on the KB along
with some new mic settings for the HC5 I also found tod
FWIW, I reported the fix for this problem at least two years ago and was

The problem was possible due to the D44-card-to-computer-case
connection. I used electrical tape to isolate the D44 card's L-bracket
mount from the metal of the computer. The bottom tab and the sides of
the L-bracket were taped to electrically insulat
Remember "computers are evil" they are out to get us. The very design
of the PC is nothing but trouble, some are so poorly designed that
current for the power flows through the chassis and power can flow
into a card through the L bracket causing all sorts of nasties, that
bracket is connected
