I just went to the local Tiger Direct to get a Firewire card for my new video camera, and I asked the tech about this speaker issue.. He gave me a good idea. He said since the speakers are powered, they have an amplifier, and so does my soundcard.. So the two amplifiers could be over-doing it..
So he said try to get the PC pushing smaller volumes, and let the speaker amplify. That doens't work so good, because even on the lowest settings in the PC output, they're loud as fuck.
So I just did the opposite.. There's a knob at the back to tweak the volumes on each speaker, so I turned them to the lowest, set my PC a bit less than half volume, and no more high pitched noise.
WOOOOOOOOOOOO.. Wish I'd thought of that before!
