What if you turn off the computer instead of putting it to sleep? Maybe it is still trying to access something even though it is sleeping, just a thought.

Let me explain my setup and then I'll explain the problem. I have a small mixer that has three or so inputs. I have my employer's Dell laptop, my Macintosh, and a cable into which I plug my electric bass. All this is served by one pair of headphones. Now in order to save on space and so forth, I have a usb KVM switch. servicing both computers. THis KVM only handles a keyboard and mouse, but you could connect video, which I do not. So, when I have the Mac and PC laptop connected and running, everything is fine. If I shut the laptop lid/ put it to sleep, but leave it connected, I get this humming noise that is not 60Mhz, but probably almost twice that. I can disconnect the laptop and then soud goes away or if I adjust the mixer controls just so, I can cancel out the sound. For some reason it sometimes gets messed up and that usually is because I have made a slight adjustment to something and then I have to start all over again isulating the sound by tweaking things. So, has anyone have any thoughts on how I might correct this problem, so I do not have to keeep messing with the controls? It could be the mixer, but I suspect there is an issue with both machines being connected to the KVM and this is a pretty cheap KVM. The KVM is not near the computers, it is under my desk.
