TV - UN50HU8550 50-Inch 4K Ultra HD 120Hz 3D Smart LED TV (2014 Model)
Receiver - Onkyo TX-SR343 5.1-Channel A/V Receiver
The only reason I am screwing around with this at all is because HBO Go is blocked on the PS4 if you have Comcast as a provider.
I've set connected all of my devices (Cable Box / PS4) to the receiver, then linked an HDMI from the receiver to HDMI 4, which is labeled as (ARC) on this model.
For about a month I had no issues. Sound went to the receiver from the Samsung Apps without issue and the Anynet+ system let me control the volume with any remote.
About a week ago this just stopped working. I didn't change the connections to anything, just out of the blue my Samsung Apps stopped sending sound to the receiver and the Smart TV reset itself to either 'Speakers' or 'Audio Out' as the only options for Sound, 'Receiver' is now unselectable.
I went back into the receiver menu and everything related to ARC is on or AUTO (CEC / ARC, etc.) I did a 'Device Search' from the Samsung Smart TV setup and it sees the Anynet+ Receiver, but it is still unselectable from Sound Menu.
Any ideas? Is it possible that an HDMI cord just ups and decides to stop working, but still passes through sound and video from my other devices without issue? Can a receiver just lose ARC capability? Did my TV ARC port just die?
