To fix HE’s Sony 4K sound-synch problem all I have to do is buy and apply the following items: (1) Catchin’ Synch, a sound-synch testing app that can be installed on any half-decent audio-visual receiver ($14), (2) a Marantz NR15065 Audio/Video Surround Receiver with Bluetooth and Wifi ($500) and (3) an Oppo BDP-103 player, which allows the viewer to adjust sound-synch issues backward or forward ($500). Never in my life have I been fleeced like this, and the nightmare isn’t even over. I’m in hell.
