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.
