I noticed this problem: with a firewire interface connected, the speakers (expecially the left one) produce a very annoying "electric" noise..and very sensible to what there is on the monitor (ex. page scrolling, bright pages, etc...) or also the mouse wheel scrolling is audible into the speakers.
It could be a ground loop, but in my opinion it's a firewire related problem.
My macbook pro had the same identical problem, solved disconnecting the external monitor.
I mean, it seems a combination of ground loop and firewire "sensibility"..
I read also that the same problem happened to several imac/macpro users.
I have the project to switch to rme adat pci card in the future so this will not be a problem anymore...but now it's a problem because the same noise goes into my amp if I have to do a reamp...
Anyone of you noticed the same problem?
