When using the smart apps on my Samsung UN55J6200 TV, i get no sound through my Yamaha HTR-4064 receiver. Cable box, blu-ray player, etc all work perfectly. Apparently, this TV model does not have ARC, which confuses me since it was produced in 2015. Am I missing something here? Hoping I won't have to spend more money on an Apple TV or some other device just so my receiver will produce sound while using those apps...
