I've got one of these. It has a display on it that shows sound being processed. I just noticed something strange - when my DVD drive (Liteon LTD-166S) is spinning up, yes, it's kind of noisy. But the NewQ equalizer shows some high frequency sound being processed. I do not have a microphone attached to the system. How is the equalizer picking up this sound?
Edit: Even weirder stuff now - I got a pair of pretty good headphones now, that are really sensitive - they don't require as high input power as previous headphones I've tried. But I can now HEAR clicks when the keys are pressed on the keyboard, and even when the mouse moves! It's not actually the sound of the mouse on the desk either - it's the mouse tracking motion. I turned it upside down, and when I pass my hand close enough to the sensors to move the cursor, but not actually touching it, it sounds just the same in the headphones as when I move it across the desk. Scrolling the wheel gives a sort of squeaky sound. It's like I can hear every bit of input that the computer gives. This is weird.
I can also hear it in the headphones when the hard drive or DVD drive seeks.
Edit #2: It seems to be the nForce2's audio processor that is doing this, as I can record it with sndrec32. 70KB MP3 of the sound. Hopefully it's not too loud; wasn't when I tested it. I set it to record the Stereo Mix at full volume - I hit record, switched to Internet Explorer, used the scroll wheel to move up and down the page, switched back to Sound Recorder, and stopped the recording. (Then I saved it as a WAV and converted it to MP3 with CDex.)
That squeak you hear is what the nForce2 apparently produced, without the aid of a microphone anywhere in the system.
