I keep getting a loud buzzing sound coming through when watching my AF9 with my Sonos Beam surround system (+ a sub and 2 play 3s). When watching Sky, this causes the sound to lag behind the screen. When watching Netflix or other apps, the picture freezes as well as sound and the resumes after the buzz.
The TV has the latest software upgrade and I've tried resetting to factory defaults with no luck.
Any ideas?
