I also ran into some problem with my laptop. Those
things are known to emit
a lot of EM waves which easily get caught by cables transmitting asymmetric
signals. When I switched all my connections between my sound card (RME) and
my pre-amp (TL-Audio) to symmetric XLR, the hum disappeared.
I had a hum problem with a Tascam US-122. I wanted to record a singer and guitar that had
an integrated pickup. The singer's mic was a condenser and so needed phantom power so
I had phantom power on, but I also had the guitar pickup plugged into the other channel.
If I turned phantom power off the hum went away.
I haven't had the problem with balanaced line either and in the end we just went for a
second mic on the guitar which avoided the hum.
