iOS 9 lightening to USB audio clicks and pops

Hello,

I use my iPhone in a Chevy Volt via lightening cable to the car's usb port. After upgrading my iPhone 6 to iOS 9, the audio consistently clicked and popped. This only happens via usb, and audio from the headphone port is fine. I confirmed this with the Music app, ibooks, iHeart Radio, and Pandora. I put the phone in airplane mode and it had no effect, meaning, the clicks and pops still existed.

I quickly downgraded my phone to iOS 8.4.1 before apple doesn't allow it anymore, and everything is back to normal. No clicks and pops.

I'm putting this out there to:

1. see if anyone else had this issue
2. see if anyone else came up with a solution
3. to let apple know this needs to be fixed in their next update hopefully.

It's a shame that this glitch happened. as otherwise, my phone was great with iOS 9.

Thank you.
