IOS 8.4 music bug..

After upgrading to iOS 8.4, when I'm playing music using the aux. port, if I get a text, the volume goes at least double. Even with the volume on the phone at max, it still goes double that. I about jumped out of my skin while driving. I use the aux on the phone and connect it to the aux on the radio in the car. No usb in the car. Anyone else experience this?

 

I've also had weird issues while using headphones (Beats earbuds). When triple clicking to go to previous track, sometimes it will beep and double the volume.
