Are there any devices to switch from these formats to AES/EBU?

Have you tried googling "AOIP to AES3", "Dante to AES3", "AES67 to AES3" etc?

There are several 16+ channel audio interface solutions:
Sonifex AVN-DIO19
Sonifex AVN-AESIO8R
CTP Systems DIO816AES
Audient Oria
DAD AX32
Grace Design m908
Direct Out Prodigy MC
Apogee Symphony Mk II
PrismSound ADA-128
Avid MTRX II
Lynx Aurora 16 (n)
There are many others that provide 16 channel high quality line level analogue audio output.
Alternatively you could use the Arvus H2-4D to both decode Dolby / Atmos from HDMI and output at AES/EBU.

While technical the HDMI spec supports up to 32 audio channels which would make this feasible to my knowledge no one has ever implemented more than 8 channels of LPCM in a product. Thus it has to be taken to another digital format or analogue.

To my knowledge this product decodes to more than 8 channels (otherwise no atmos decoding), so if you have the speakers output is 15 channels.

HDMI supports 8 channels of lossless high resolution audio.
Only HDMI eARC supports 32 channels of lossless high resolution audio.

That does not really matter as the objects are included in the bitstream (channels) carried over non earc hdmi and it becomes aoip after decoding.

Yes it decodes to more than 8 channels, HDMI 1.x only supports 8 channels of PCM Audio, HDMI 2.x is specified for 32 channels of PCM however to my knowledge no device has ever implemented support for it.
The person I was replying to was asking why it couldn’t output LPCM over HDMI after decoding rather than over AOIP.

No you can’t that article describes how to extract a Atmos stream from an mkv file render it with the Dolby Reference Player (which you have to pay $400 to get) to a specific speaker output format then remux the multiple channel PCM back in to the MKV file.Absolutely , for a long time now
How To Decode and Play Dolby TrueHD Atmos on Windows and macOS
Yes, you read the title correctly. Here is a little background and all the information you'll need to decode and play lossless Dolby TrueHD with Atmos on a Windows or macOS computer, without the need for HDMI output. Housekeeping There are two codecs used with Dolby Atmos content. Lossy - Dolby D...audiophilestyle.com
What you can do on macOS if you have a 16 or more channel audio device is get a discrete output suitable for speakers from Apple Music only if you set the speaker format for that output in Audio MIDI Setup to an appropriate one involving height channels.
You cannot directly play an MKV containing Atmos formats and render it to discrete outputs in realtime only in software.
You cannot render streaming services to discrete outputs in realtime.
You need an external device connected via HDMI.
To be blunt there is no good technical reason its entirely Dolby protecting their income stream from licensing to hardware vendors.

believe they misspoke, this device has HDMI 2.0 which is 2013 era. Should still be enough for full quality 4K UHD media playback, but leaves something to be desired for gaming.
Yep, I meant no HDMI 2.1 (which released in 2017(!)). So no 4K 120hz/144hz support with VRR. But I guess the point is you use eARC for everything and just have everything connected to your tv or HDMI 2.1 switches (if you don't have enough ports).

On the face of it, the H16A looks to be the decoding solution that a lot of us have been looking forwards to.
However, it doesn't do sample rate conversion, so you'd have to manually change the Dante sample rate every time the source required it.
I think Dante device can auto negotiating the sample rate between devices, so your concern might not be valid.

I would love to be proved wrong, but to the best of my knowledge, Ravenna can negotiate sample rate changes, but Dante cannot.
Dante will negotiate the same rate to the lowest common denominator supported by all patched devices on the network at patch time. So if the network was originally configured to 96k and you added a 48k only device the whole thing would be configured to 48k.
Because any device on the network can send or receive audio and because changing sample rate interrupts audio in Dante’s intended market it makes no sense to allow on the fly negotiated sample rate changes and would be actively dangerous to use in live sound reinforcement.
Many Dante devices will have a SRC and convert from the device’s rate to the configured Dante network rate instead.
Yeah, I think they will have to add this capability to the H16A or it'll be DOA. It's table stakes for a Dante device that will regularly be getting 44.1k, 48k, and 96k input (from HDMI) that it needs to re-transmit over Dante.
