Recently bought the 5015 and love it except: any dialogue that emanates from the rear speakers is associated with static under all surround sound modes. Of course the normal dialogue sent to the rear speakers is very low levels, but my rear speakers are close enough to our seating spots where you can hear the static voices. Worse when dialogue is off screen because I think the processing is designed to send that dialogue to rears at normal volume. Changed the speakers and it still happened. Does not happen with multichannel stereo setting when all speakers are fully engaged. the receiver is 7.1 capable but I have it set up as 5.1. Am I missing something? Can anyone help? Thanks.
