Sonos Arc via eArc with AVR

I have an existing AVR setup (with sonos connect as an input) and currently have lots of sources (e.g. sky, PS5, Switch etc.) running through the AVR then into my TV.

I am adding a second system in another room, but would like to be able to use all of the same sources, via the AVR.

I'm wondering if I can use the AVR's second HDMI output into a TV in another room, and then use the TV's eArc HDMI output into a Sonos Arc (along with era 300s and sub).

This would allow me to use the AVR as a passthrough source for the TV with audio coming to the Arc via the TV.

I cant see a reason why this shouldn't work, as as far as the Arc is concerned the AVR would in effect just be the TV's sources, but wanted to check if anyone else had done something similar before blowing a load of cash on it in vain!

So if understand correctly, you have an AVR with for example a PS5 connected to it.

You want to take the audio/video from the PS5 and via a second HDMI-Out on the AVR send it to a HDMI-IN on a TV.
So essentially the AVR becomes the source for the TV in a similar manner as a cable box.
You want to connect a Sonos Arc to the TV via its HDMI-eARC
In theory it should work as long as you select the HDMI-Input for the AVR on the TV
I personally haven’t tried such a setup.
Do you already have the Arc and Era 300’s?

Thats pretty much it, yea. I can't see why it shouldn't work. Presumably running the Sky box or PS5 to to the TV via the AVR is no different to plugging it straight into the TV, with the TV's eARC then plugged into the Arc.

If the TV’s are using different resolutions, the receiver may not support this simultaneously.

No requirements for both to be on at the same time, and im pretty sure the AVR can support two totally independent outputs but I will check. It's a Yamaha RXA6A.

Supporting two independent outputs is easy if resolution and other settings match. If things do not match what I have seen on three different systems is that the source device negotiated the best common output settings so all connected could play.

Really ugly when your 4K big screen gets forced to 720 because you tried to add that old spare, small screen TV to watch in another room.

Yea that makes sense. But both screens will be very similar though, 4k 120hz+ etc. Reckon it should be a goer but will try and get my hands on someone's device to test it.

You are sure the second eARC on the receiver is an output?

Does the receiver's eArc capability have anything to do with it? Would it even need eARC? The receiver will be outputting audio and video via HDMI to one of the TV's HDMI inputs, that is all the receiver is doing, effectively passong through the source to the TV. The Sonos Arc will be connected to the TV's eARC enabled HDMI inputs, allowing the TV to pass the audio to the Arc via eARC, no?

Just as a note of caution, based on what I see on Yamaha’s information page, this device passes through eARC signal, but doesn’t create them. So the point

is especially important.

Wouldn't it be the TV that creates the eARC signal? For example, what is the difference between the following two signals chains:

PS5 > TV (HDMI2) > TV(HDMI1 - eARC) > sonos Arc

Vs

PS5 > AVR > TV(HDMI2) > TV(HDMI1 - eARC) > sonos Arc?
