Need some help, please

[JCanada]

Hi, me again. The last round of suggestions I received were very helpful. I now have another scenario I will need some help with. I own a Sony X750 4K 65inch smart TV. I have an Onkyo RZ-820 as my AV receiver hooked up to the TV through an HDMI cable to the TV's ARC input port. I would like to connect my Yamaha A-S801 amp to the TV via optical cable. I would like to have a different set of speakers hooked up to the Yamaha, and a different set of speakers hooked up to the Onkyo. I wish to connect a second ROKU streamer to one of the TV's input ports. I already have a ROKU hooked up to the Onkyo.
Here is my question: If I have the Onkyo AV receiver turned off, can I turn on my ROKU, turn on the TV, and turn on the Yamaha, and listen to the Yamaha through the optical cable coming out of the TV?
I primarily listen to DEEZER and SIRIUS/XM through ROKU. I would like to listen to 2 channels on a different amp than the Onkyo.
Would I be able to have one ROKU streamer hooked up to the AV receiver while having another ROKU streamer hooked up directly to the TV?
My goal is to switch from the Onkyo to the Yamaha when I wish to listen to 2 channel. I will have 2 pairs (4 floor standing) of speakers. 2 speakers hooked up to the Onkyo, and 2 speakers hooked up to the Yamaha.
I know this is a long question/post, but this forum has given me great advice in the past. I eagerly await any feedback, questions, clarifications, etc...

Why do you want to do this?

If you are using ARC from the TV it may not be possible for it to simultaneously send audio out of the optical connection. But, if the settings in the TV allow for digital audio output over optical then it should work just fine.

If not, then you may be able to use optical directly from the Roku to the receiver.

I prefer to listen to 2 channel sound out of my YAMAHA A-S801, rather than the 2 channel sound out of the ONKYO.

Thanks. I have a few more questions, if you are willing to give me your advice.
If I use the optical out of the ROKU, will I still have the ( (--on TV screen--) ) interface for the ROKU menu?
What happens if I use another input port on the TV other than the ARC input port? If I hook up the AV receiver into the TV through another port other than the ARC port? Example: I hook up one ROKU to the AV receiver, and the receiver to the TV through the ARC port, or through another port. Then I hook up another ROKU to the TV through another port on the TV that is free? I will have 2 ROKU's working. one hooked into the AV receiver, and one ROKU hooked up directly to the TV. The ROKU to the TV will be the one I will want to use for the optical out of the TV to the YAMAHA. A bit to process yes, but I am in an audio/hi-fi forum, so I hope I can get some suggestions/help.

Any source connected to your TV that is currently playing video, will have whatever interface it offers available on screen.

Optical audio is just a different way to move audio from a source to a destination. The problem with many modern products is that they don't have a digital audio optical output on them anymore. This includes Roku products. So, if you want to get the audio from the Roku to the A/V receiver, bypassing the TV, or going to the receiver through optical and the TV through HDMI you will need to test things out. Since your setup is unusual with the request for two A/V receivers, it makes things more interesting.

The second Roku, connected to the receiver directly, is a normal setup. We won't worry about that one at all. It doesn't really matter that much because that one will work just fine.

But, the one connected to the TV will depend on the TV itself and how it handles the ARC and the optical audio outputs and whether they can be simultaneous. They very well may be available at the same time, in which case the receiver with ARC and the receiver connected via optical audio would both be receiving audio from the TV at the same time, depending on what source was playing on the TV.

Another option is to use a HDMI to HDMI+Optical audio extractor.

They have 1080p models for about $20, but this one will properly work with 4K sources (it says)...

So, you get your HDMI video up to the TV and you get a digital optical audio output as well to connect as you want to. Audio will not be in HD audio formats, but will be a good 5.1 mix.

I thank you for the reply. Much appreciated.
if I may, can I ask you a few more questions?
I will not have a second AV receiver connected, but an integrated amplifier. So my setup will be one AV receiver, and one integrated amp. Regarding the extractor you suggested, I have a question.
If I use it, will I still have an on TV screen interface for my ROKU? For me, that was the whole point, without the on screen ROKU interface, it is no fun. I am looking to have the on TV screen interface, while going out of optical from the TV to my integrated amp.
Again, any feedback is appreciated. Thanks again.

The Roku generates its own on-screen menu. If you can see the Roku, then you can see all the menus that the Roku generates. So, yes, you will see the menus.

Thanks for the advice. I connected my YAMAHA-S801 to the TV with an optical out, and a different set of speakers connected to this amp. (ONKYO AV receiver has a different set of speakers connected to it). I turned off the ONKYO AV receiver, powered up the YAMAHA, streamed SIRIUS/XM through the ROKU, (still connected to the AV receiver, AV receiver still connected to the TV through the ARC input), and the sound came out through the YAMAHA A-S801. I muted the volume on the TV, and the YAMAHA sounded great. ROKU interface on the TV was the same. Results are exactly what I wanted. Thanks again.
