EX1r audio buzz
 

Just received my new Sony EX1r and discovered a very annoying faint audio buzz. Buzz is audible during monitoring when using either internal or external audio. Doesn't appear to record onto the video itself. Called B&H and am now shipping the camera back for an exchange. I also have the EX3 and have had no similar faint buzz issue with that camera. Anyone else experiencing this issue with the EX1r?
