I emailed Anthem & they said to connect the i2s cable to HDMI. I know it’s not in their manual. I’ll email them again to re-confirm and this time, I’ll ask for the AVM’s i2s-HDMI pin configuration. I’ll let you know the outcome,
Here is an explanation from my DAC distributor explaining the same thing to another question like this: https://www.kitsunehifi.com/?attachment_id=9181

You’d think if AVM 90 supported I2S for some incomprehensible reason, you’d think Anthem would be talking about it non-stop. They do talk about Roon Ready all over the place, which it doesn’t have (and at this point probably never will). But not a single mention of I2S, although it’d be a great marketing point, world’s only AV Processor with the world’s most pointless two-channel input…
Not that the idea of connecting RS-130 with AVM90 made any sense, other than taking two random expensive toys and throwing them together for the sake of expensiveness…

Hi joyofmind, as HMANAZ explained, I2S is a protocol for audio transport over a HDMI cable/connectors. A first basic and direct layman’s question to Anthem could be: does the AVM 90 accept the PS Audio I2S standard (or deviates from that and how)? To be sure, they may share their pin connection scheme to show how to make a good and working I2S connection, even if it were a bespoke one (with all it’s risks for you and your equipment).
@Jobbie Thank you for your suggestion.
BTW, I’m still emailing Anthem for my proposal to add an i2s port on the AVM 90.

Please let us know if it works to your expectation!
Oppo (I have one) outputs HDMI not I2S. The response from Anthem does not show that you can plug an I2S device into an HDMI AVM. Check @BorisM point above. You are going to break one or both if you do!
@BorisM’s “uncle” shares more about I2S vs. HDMI → https://youtu.be/hY3uxXEJ9bA?si=yzy9Qn68nvDFB4Zg @joyofmvid FYI
HDMI cables can transfer I2S signals but that does not mean I2S is part of the HDMI Spec. If so, can you find any mention of it? I don’t think so… If it is why don’t other AVM manufacturers market this?
Wow…
She probably asked them the same thing 50 times, and they finally wrote something, anything, to get it to stop 
I2S (the real thing) is an electrical and signalling specification for internal traces on a PCB, for moving digital data on an internal boards, and does not (can not really) have anything to do with HDMI. I2S as an external connection can’t be part of HDMI spec, because HDMI is a real, professional standard, and I2S does not have any standards at all.
Really, of all the terrible things to come from BS Audio, putting I2S on HDMI cable is probably the second most terrible, right after pushing I2S as an external interface itself. I can understand why they’d do it – the entire company does not have engineering resources to design a working connector of their own. And now we get all the people who obviously have no idea what HDMI, I2S and all those other funny abbreviations mean and what they are used for going around demanding that someone get it working for them because the cable obviously can be plugged from Point A to Point B.

A standard is a standard if everyone accepts it as such. To say only hdmi is professional is your opinion and disregarding of efforts of Indeed a small company of establishing a new connection type using an industry standard. This is economically sensical, although potential confusing, like in this case. Alternatively, alternative are also available, commonly usb and xlr.
However, there are lots of people unbothered and happy users of I2S, whatever your opinion of its founding company.
Hi to everyone who has been commenting about i2s.
I am still in progress of “Proposing Anthem to support i²s on AVM 90s”.
I know the i2s protocol is not an HDMI protocol: In fact, i2s transmission is as follows:
For full details regarding the i2s communication protocol, see https://www.digikey.com/en/maker/tutorials/2023/what-is-the-i2s-communication-protocol#:~:text=I2S%20is%20a%20synchronous%2C%20serial,audio%20in%20a%20serial%20fashion.
I know I’ll need an i2s cable with a custom pin configuration on each end of the cable (one end is for the RS130 pin configuration and the other end is for the AVM 90 pin configuration). Both ends of the i2s cable will have an HDMI CONNECTOR.
Now regarding Anthem AVM 90: Anthem has emailed me again. They said they’ve assigned Specialists to look into the matter. They said, please wait.
In turn, I’m asking everyone hear to be patient. As soon as I get a response from Anthem, I’ll let you know.
Good thing about standards is that there are so many of them
Something that does not even have a defined pin-out over the same (HDMI) wire is not a standard. Let alone professional, but then nothing from BS Audio is professional.
Nothing in this sentence makes sense. And there is no standard, either.
Sure. We have happy users of audiophile fuses, $1000 USB cables, and God knows what else here, too. They are happy, as people of low IQ often are, because they do not know any better, but it has nothing to do with any alleged performance benefit of their little doodads.
Oh, and BS Audio did not “found” anything (that would require some technical competency, and Uncle Paul will not pay for that). They’ve created a Rube Goldberg monstrosity of an internal transmission mechanism and a common (i.e. they could get them cheap) external connector to make something that has only one function, to sell more BS Audio products.
No offense, but instead of reposting pictures that you obviously do not understand, you should just sit down and read up on digital audio a little bit. Just because there is an HDMI connector meeans absolutely nothing. Anthem has HDMI inputs, it expects HDMI signal on them, with video and everything. If Anthem had somehow made a transceiver that can handle both, and somehow stuck it on one of the HDMI inputs (probably technically possible, but not at AVM90 price point), they would advertise it left and right. They already advertise even things that their receivers do not do.
There is no point in doing what you are trying to do anyway, because there is a correct way of connecting 130’s digital output to Anthem’s digital input – using a plain old HDMI cable ($15 at the nearest Office Depot) from 130’s HDMI output to Anthem’s HDMI input. Nothing else is needed.
Edited June 17, 2024 to be more specific with my request to Boris.
Please, let’s be respectful. With lines like this, it makes the rest of your post sound like Blah, Blah, Blah. I ask that you stop filling threads with posts containing insults.
Boris, let them believe in you!!!
To err is human and people err as long as they live.
Let them all do it until all their houses 
explode:boom:
The boxes don’t even cost 100💵.
Let them do it, you’ve tried everything. Many people let others think and no longer think for themselves.
Stay 
peaceful with each other:v:t2:and also accept the opinion of Boris, who really speaks frankly
and tries to enlighten you. Don’t fall for the HiFi & High End Mafia.
With that in mind, Bonte✌🏻
Honestly,m I prefer not to care what terminally stupid people might think about… anything, really.
Your problem isn’t that you know nothing about this stuff. Most people do not, and do not really need to. Your problem is that you somehow got it into your pretty little head that you do know something, and keep insisting that people tell you what you want to hear instead of listening to multiple people, not just me, telling you that it does not work this way.
Good luck burning out more than $10K worth of electronics.

May the force be with them…10,000 dollars will go up in smoke…but I think there will be a big outcry then.
…why did I listen to the hi-fi mafia and not to the people who tried to enlighten me here.
Boris! You’re just cool. I like it when someone speaks frankly and you don’t give up and keep answering. That shows your effort to educate people. Unfortunately, it’s rarely accepted.
It’s a shame, actually…if people would educate themselves, the world would look completely different because people wouldn’t let themselves be manipulated like that.
*that’s my opinion and I’m not attacking anyone personally and I hope it won’t be interpreted that way.
Never could have thought B&B joined and wishing the both of you a happy future! 
Re: My request for Anthem to support i2s communication
Anthem made a decision. This is what they said in their email:
We have the final word on this project you are attempting, and its not possible, unless there were actual internal hardware changes to the Anthem itself in how it would accept the i2s data stream. So I guess you could say theoretically possible but not feasible.
I agree with Anthem’s decision. If i2s support was possible with only software changes then they might of considered my proposal for the near future. I thank Anthem for their efforts. IMO, they are a great company & have always considered my requests seriously.
