Same discussion happens at Linux Audio User Mailinglist in the moment.
My advice is to use balanced/ symmetrical cables if the Edirol and your
mixer have balanced in- and outputs.
Cheers,

If you can get hold of a transformer PSU for your laptop
that is a very reliable solution. It's not really a question
of ground "loops", so much as switched mode power blocks tend
to float at up to 80 volts above ground, especially the cheap
ones. They throw off horrible little spikes at 100Hz whe
one solution i heard of is to use a psuedo balanced
cable, a normal audio cable with a resistor soldered
into one lead (iirc)
all the best

Although you should use this solution at your own risk, I've solved
this problem by using a 3-to-2 prong adaptor ... The more expensive
solution is some kind of power conditioner, I believe...

Hi all,
I've had an annoying hum coming from my edirol FA-101 when I hook it up
to PA systems and have finally figured out that it occurs only when my
laptop is plugged in and not running on batteries. The FA-101 is also
plugged in (boo 4-pin 1394 connections...) and then the amps I run into
