Using a hu6950 55 inch "Smart" TV, the setup is STB to Marantz receiver to TV. HDMI 4 is used for ouput via receiver with ARC turned on both TV and receiver. 

 

Tried to play video from apps (Netflix or Amazon video) and like many others posted on the net, The Anynet + CEC through ARC (HDMI4) could not have consistent handshake between receiver and TV. Gave up the ARC idea and hoping to get discrete channel audio via Optical audio, this does not work either.

 

Tried out many options, set audio to PCM, turned off Instant power on, TV factory reset, smart hub reset, audio reset, different HDMI ports, different HDMI cables, powering up sequence, manual switch to Audio out... etc. Not only is Anynet not working, I could not get Optical audio to turn on either (no light through the cable). Video quality is great, if only I enjoy silent videos.  The only available sound option is through TV speakers or through analog RCA output.

 

Tested out the Optical cable directly from STB to receiver and it is working fine. Is there a way to force this smart TV to be dumber so it could turn on optical audio output always?

 

Had a LG TV prior and never seemed to have issue this frustrating...

Is the receiver ARC compatible? When you connected the STB to receiver via Optical, did you see light on both ends? Have you tried calling in to have a service reset?

Receiver is ARC compatible. When Optical is outputing from STB to receiver, it is working fine.

I did not call in to have a service reset, would this help or suggested as a trial and error?
