a power inverter will do that. i have the same problem, but i'm not sure how to fix it.
i am running a laptop carputer set up. when the power invertor is on there is alternator whine and a weird crackling noise. i assume its a ground loop problem, but i hooked up an isolator the the audio out and it didnt fix it . any ideas/suggestions...i am using a usb external sound card that i got from best buy http://www.bestbuy.com/site/olspage....=1122654484359 . when the laptop is on battery it sounds great.
EDIT: I saw an add in the paper yesterday that said..."You can get IT at ebay...whatever IT may be"

an inverter is one of the worst ways to incorporate a computer in the car. They are inherently messy and induce so much noise it's unbeleavable. For the same amount of money that a GOOD inverter would cost you, you can get a GOOD dc-dc power supply. Not only will it be smaller, but it incorporates much more into it and is 100x easier to implement and use in a car.
Not just talking about start-up and shut-down procedures here.
