I bought a pair of Creative Gigaworks T20s the other day, and as soon as I plugged them in I noticed the one speaker (not the one the power goes into, the one connected to the main one by a power/audio out cable) constantly makes a whining noise, quiet but noticable when playing quiet music. The noise continues when the speaker isn't connected to the pc audio out. I updated my drivers anyway, tried completely isolating my speaker cables from any other cables, turned off everything except the computer itself, nothing. No change in the frequency or volume of the noise. I'm at a loss.
