I have connected TV HDMI ARC to receiver ARC. Sounds work great and all speakers(5.1) plays if i play anything on receiver itself (net audio, pandora, apple air play) but when i play anything though samsung Smart TV i only get centre and 2 front speaker playing. The rear/surround speakers don't play sound. Am i missing anything. Anynet+ (HDMI-CEC) is On Auto Turn off Yes and Receiver ON on samsung TV.
