I have the same problem going over the internal sound card, and it is
more intense there. The odd part is, the lower the latency, the more
intense the hum; and even weirder, I CAN EVEN HEAR THE HUM WHEN THE
COMPUTER IS HOOKED UP TO SPEAKERS THAT ARE TURNED OFF. So you can
actually hear the hum; it's just that whatever sound adapter is hooked
up, firewire or interal, amplifies it.
First I thought it was hard drive noise; but I tried putting Jack's
tempfiles on a ram disk and that had no effect.
Could it actually be that the CPU itself is causing electromagnetic
effects because it has to work so hard?
Curious.
