when i use my m-audio project mix with my laptop i get a constant, very loud
hum/noise - this only occurs when i have the laptop plugged in and disappears as soon as i
unplug the laptop. I was aware that this problem might occur but i'm f**ked if i can
remember how to cure it - i don't want to disconnect any earth wires in the plug,
i'm sure there was a mod i could do to the firewire cable to solve this - but what?
You didn't say what laptop you're using. I use an Apple PB and an M Audio 410 and the 410
is powered by the 6 pin firewire port, if you plug the 410 into the mains you get all this
noise you mentioned. Don't know if this helps.
