Sorry if this is a simple and commonly discussed issue. I simply don't even know what to search for to see the answer. lol

I just bought a 77" Sony A80J and want to use my Yamaha RX-V679 but I'm having some issues and have a few questions. The main issue is that I cannot get sound to the receiver through any HDMI connections. I can only get sound through the optical connection.
1. I am using the built in Sony platform for all my streaming services. It's as good or better than my Roku Ultimate so I wanted to simplify things.
2. All firmware on both devices is up to date.
3. I am running a 5.1 speaker set up with a decent set of Polk speakers...nothing special but good enough for me.
4. When trying the HDMI sound option I am using the eARC ports on both devices and have tried other ports.
5. All cables are rated appropriately and I've tried different cables...again all rated properly for these ports.
6. I don't use this room or setup for anything other than movies/tv, so streaming music or any type of other music device is irrelevant (turntable, etc....)

So here are my questions.
1. Am I losing anything by using the optical instead of the HDMI?
2. If I am not using the upscaling of my receiver, doesn't it make more sense to use any devices (Nintendo Switch, Apple TV for my yoga programs, etc...) through the TV instead of the receiver?
3. Would I be wasting money by buying a new receiver if I am only using it for audio because the TV would probably be its equal unless I spend a decent amount of money on the receiver? I don't have a problem dropping 1-2k on a new receiver if it will genuinely offer me a large upgrade in sound.

This is my first foray into a setup of this quality so excuse my ignorance and thanks in advance for any help offered.

Oh, and the picture on this TV is unlike anything I've ever seen, it's stunning.

I'm not familiar with eARC, but the HDMI issue could be due to the fact that the TV only has an HDMI input, not an output.

In terms of specific answers to your questions:

1. In terms of audio, the answer is no.
2. The answer is yes and no. If all of the devices mentioned are 4K, it would make sense. That would, however, necessitate the TV having enough HDMI inputs to accommodate all of the devices. It isn't the case.
3. If your devices are 4k, it's probably worth it. All of them could be accommodated by an AVR, which would then send their signals to the TV.

Using the TV's streaming capabilities rather than the Roku, in my opinion, does not simplify things. All components are connected to the AVR in the simplest system, with the TV serving only as a monitor. As you can see, using the TV as one of the source components only muddies the waters.

No disrespect, especially since it's my 1st post here, but EARC is a bidirectional audio and video transmission protocol. Video in from an AVR, if the AVR is the video switch, and or sends audio in the higher formats, such as DD+ and Atmos back to an AVR that also has eARC.
I'm having a **** of a time with a new A80J and my older non eARC, but ARC Pioneer Elite SC-72. I'm stuck with either better picture or better sound depending on which unit, TV or AVR is the source switch. Found this SHARC-V2 unit for that converts signal to be used with eARC TV and non eARC AVRs. It goes between the eARC in on the TV and any non ARC HDMI on an older AVR.
Anyone have any experience with this.
Thanks, I love geeking out on this stuff!
