For some reason, the iPhone causes interference with my external speakers. Now, I am not even connecting the iPhone to the speakers. The interference is random sometimes and is also triggered by when I get a phone call or text message or when I sync with my Mac.
The image at the top right is an setting you can configure when you hook up your iPhone to speakers. Note, I do not get this option, because I am not hooking up my speakers to the iPhone. It just causes crackling and popping noises that come out of my speakers. Turning off the speakers don’t help. I can turn on the airplane mode feature, but then I won’t get calls, text messages, emails and web.
One person said, you will just get used to it…
blackberries do this all the time. After a while you just get used to the sound
I try to put my phone a good distance from my speakers, which helps a lot.
