Has anyone experienced any audio pop/crackling with the iPhone 6+ using audio out through the lightning port in their car? Have hooked up our iPhone 6, iPhone 6+ and iPad mini with the lightning connector to the audio input of the car (via USB) and we're getting consistent pops/crackling with the 6+. When we use bluetooth streaming with the 6+ the pop/crackling goes away. (The sound quality in the car with all devices is better through the lightning connector, so that's our preferred setup.) I thought that we possibly had a defective iPhone 6+, but then I tried it in two of our iHome clock radios and there's no audible pop/crackling when getting audio through the lightning port. I also thought maybe something with the iPhone 6+ radios was causing the interference, but I tried it in airplane mode this morning and I"m still getting the pop/crackling. Any ideas as to what's going on?
