Has anyone heard about the problem with hissing/high pitch sound when you plug the iPhone 4S into an aux cable in a car?

I have this issue. It seems widespread. Only happens when I'm listening to music in the car.

Has anyone encountered this?

You connecting it via the headphone jack or line-out via the dock connector? I'm getting a high-pitched whine when it's connected via the dock connector to my car's iPod kit. I didn't get this with the iPhone 4 or any previous iPhone models so something changed with the iPhone 4S...

I get the 'alternator whine' or so im told everytime i try to charge the iphone and play it through the stereo through aux at the same time.

I had that on my 4th gen iPod Touch. Swapping it seemed to do the trick

(But for me it happened only with music going through the dock connector. Music through headphones / the headphone jack was fine.)

Same here in a Hyundai minivan using a Monster cassette input with my new iPhone 4S. Happens with all audio output through the headphone jack in the car. Doesn't matter if it's charging as well or not. Not a problem when using earbuds. I've never had this issue with the following using EXACTLY the same setup: iPhone, iPhone 3GS, iPod Touch (4th G), iPod Nano (1st and 3rd G), iPod shuffle (3rd G). This is obviously a iPhone 4S issue.

There is a thread over on the Apple forums here: https://discussions.apple.com/thread/3397942?start=0&tstart=0

It seems to be a rather widespread problem. Please submit feedback here: http://www.apple.com/feedback so we can expedite a solution from Apple tech.

If it happens only when the phone is plugged into power, you might be getting a "ground loop". You can get a "Ground Loop Isolator" at radio shack or probably Best Buy to take care of that.

If it happens when the iPhone is running on its battery then it is not a ground loop, and the isolator won't help.
