I think pipewire can do this. One of my ex-colleagues used to do this sort of thing and, at that time, I believe he used "jack", which was superseded by pulseaudio, and then pipewire. Unfortunately I don't know any of the details but this may be relevant:

And:

Now the question is - Does the Pi 4 run a version of Linux which contains pipewire?

I mentioned pipewire as I thought that Raspbian had already switched but AFAICT it is still on Pulseaudio so the thread I Iinked to is more relevant than I thought. So you might be able to do it with PulseAudio. But I believe that Manjaro and/or Arch have pipewire at least available.
I only have headless pis running Ubuntu ATM, all without any audio, so none of them have either pipewire or pulseaudio installed, so I can't check how well it works. But pipewire is definitely in the raspberry pi repository for Ubuntu.

I don't see why separate, expensive, Pro devices should be required.

If a Pi can read an incoming Ethernet Roon audio signal, and output it as a USB stream to an external DAC, then why couldn't it read an incoming SPDIF audio signal, and output it to an external USB DAC?

The simple answer is that the RU6 DAC doesn't have the drivers to do this. All of the Audio Interfaces use software loaded on a the interface to accomplish this. As I said before USB isn't an audio interface it is a data transfer interface. Much different.

Anyway, I found out that Roku boxes have squeezebox support. Roon supports squeezebox and can transfer over ethernet. Do you have an ethernet port on your Roku?

If you don't have an ethernet port, you could get a HAT on your pi that has SPDIF input and then transfer that to Roon and setup your RU6 on another of the USB ports on your pi with a usb-c to USB-A cable and there you go. No expensive audio interface. I don't think you would even need to go to squeezebox to do it this way.

@DBaldock9 I found a HAT for you that has a SPDIF input that is supported by RoPieee. It's the Allo Digione. This will do it for you. Just set it up the way I described an you should be golden. https://allo.com/sparky/digione.html

Of course you will need to buy Roon too.

I see that the MainSqueeze channel (app) on Roku can stream music to my Roku --- but what I want to do is watch TV (on various Roku channels - Philo, Acorn TV, BritBox, Amazon Prime, YouTube, etc.), and have the audio (which comes out on the HDMI port) somehow be connected to the input of my Cayin RU6 USB DAC. Right now, I have a HDMI->SPDIF (optical) adapter, which is connected to my 4x4 Optical Matrix Switch, and then to several DACs with SPDIF inputs.

This whole series of posts, is due to my desire to be able to connect DACs that only have a USB input, to the various non-PC audio sources in my system.

I know that before RaspyFi became Volumio, a web page [ http://www.raspyfi.com/the-right-usb-dac-for-your-raspberry-pi/ ] was created, that lists various USB DACs that could be connected to the Pi, for listening to audio.

The only reason I've mentioned Roon, is because I've seen it mentioned that some people use a Pi as a Roon Endpoint Music Player, with an external USB DAC connected.
I use JRiver Media Center (on Win10 & Linux) to manage my music files, and don't have any interest in buying, or setting up, Roon for myself.

DENON POA-8000 / PRA-6000 (1981)​

State of the Art mono power amplifiers introduced in 1981 by DENON. I think the POA-8000 can easily compete for the best looking monoblocks ever. It is using a ultra-high stability and ultra low noise construction with DENON's Non-NFB Class-A design. This design will prevent transient distortion and it will provide excellent dynamic characteristic. A high speed, high linearity 3-stage powerful darlington power stage is used while DENON's real bias circuit is enabling high efficency Class A operation. Large VU meters and Digital display adds the final touch to this beautiful power amplifier. The POA-8000 set was partnered by the equally well designed and handsome DENON PRA-6000 preamplifier.
