Anyone find a solution to this problem? I just got my replacement note 3 and it started doing this. Anywhere I plug in AUX it does it. When I use Pandora it pops at the beginning and ending of every single song as well as the beginning and ending of every notification sound. I'm wondering if this a hardware issue and if I should request another device.
