How do I get rid of the speaker noise?

Hello people

With my PC I have the problem of getting noise on the speakers.

When I turn the volume a bit high there is an annoying noise.
Same noise happens when I am connected to the Internet with a 56k modem (HSP
MicroModem).
It sometimes looks like pure white noise, other times looks like my speakers are
receiving radio signals.
There are no people that do radio transmissions (e.g. hams) nearby but I live
near an airport.
If I disable sound in MS-Windows' volume control the noise stops but it's
difficult to listen to music :)

What can be causing this noise on my computer speakers and how to get rid of it?

Sometimes muting the microphone input helps.

I know I have a ground loop in my system somewhere that causes some
wacky annoying noises when I have 2 computers both plugged into a
single speaker system (which has 2 inputs).

Are you pluggin your speakers, modem and computer into the same
outlet? If not, try that and see if the problem goes away.

Best Regards,

Not, in fact I don't have a mic and muting the Audio CD input cures a lot of the
noise.

Yes, they're all plugged into the same outlet, via a line filter.
I've found that muting the Audio CD (!) input cures the problem.

That's not surprising. The analog audio cd input and the microphone
input aren't all tha tdifferent from each other--they're both analog
inputs that can have noise on them even if they're disconnected.

Glad you solved your problem.
