Hallo,

I assume you're using a laptop. I've noticed a
similar issue on other
laptops (Dell notebooks and Apple powerbooks have similar issues). It's
simply because when the laptop is hooked up into a wall, the current
that travels near the main motherboard in order to get to the charging
battery causes interference. You may want to try using your laptop
hooked up into external power but without the battery in the laptop
itself and if the noise is then gone, then that is definitely what is
causing it.
I didn't try that, but I'll do, maybe tomorrow.
Other option is that even if the battery is out and it
still makes
noise, that your external power connection is too close to the USB
controller of some sorts (or even the USB connector) causing similar
interference.
I could verify now, that it must be something with the power supply. I
took everything except my amp over to my friends room, plugged it into
her amplifier and didn't get noise anymore.
Thinking about it, I have a whole bunch of electrical devices
plugged-in in my room. Maybe I have reached the final frontier for my
connections and need to get a new one. But I'm glad, that the hardware
and especially the notebook seems to be okay.
ciao
