Is there a DDC or ? that has I2s and USB inputs and Coax output?

All DDCs that I’m aware of convert USB to SPDIF and usually i2s.

None degrade i2s to SPDIF.

Buy compatible components.

thanks for the response

I thought I had compatible components. The Eversolo A8 has multiple digital outputs but they only work when streaming. If you use another input or HDMI Arc it shuts them down and does analog or I2s out. I had planned to use my Denafrips Hermes DDC to Lumin U2 via USB for streaming and the Eversolo for TV via HDMI ARC to the Coax on the DDC. The Eversolo is a new item and the internal architecture wasn't known to me. My Bluesound Node has no issues with HDMI Input to Coax output. I'm told HiFi Rose RS150 will do what the Node does........

The Node does all this so effortlessly that I never even thought this could be a thing

The PI2AES https://www.pi2design.com/pi2aes-980244.html

Outputs all outputs simultaneously as does the Pi 2 Design - Mercury Streamer V2

thank you for the reply

Yes but no I2s input
