From my experience, some computer speakers, you're not going to fix it. The
amplification in those is so cheap and garbage and unfiltered or anything,
it's just something you'll have to deal with more than likely. Grounding to
a cold water pipe may not help either though as most often if you do it
after the meter, supposedly the meter can isolate you from that actually
grounding though I don't always trust that, but worse than that, a lot of
times either the electrical can be grounded there which should make RFI
issues worse and when I was new and starting out, my water pipes acted as
part of the antenna when I did that. It never showed up on the SWR or
anything, but it caused a lot more RFI than it was supposed to fix and my
electrical is grounded separate from the water pipe because I have a well
and most of the line from the well to the tank in the cellar is PVC anyway
though I didn't know that at the time.
Short version is though, half the hams I know, myself included go through
computer speakers in some way, shape or form and there's really nothing most
of us can do about it, a lot of us around here have tried everything there
is to tru and nothing helped short of just turning them off and using a set
of headphones in my case. The sighted hams just shut them off and leave it
that way.
