Can a Sonos Arc Ultra w/ Era 300s work with Roon Nucleus and CA Evo 150?

I have a modest collection of DTS CDs, DVD-Audio discs, SACDs and the new Blu-ray audio discs. Fortunately, my Sony UBP-X800 and Sony UBP-X800M2 players can play them all and can also bitstream Dolby Atmos and DSD signals from files on a connected thumb drive.

Not to barge in but some AVRs can play DSD from USB.

Yes, and my AVR can handle a DSD two channel bitstream over wifi as well. DSD multichannel bitstreams are an issue and different devices will do different things with them when playing them over HDMI or a network connection. In many cases, the DSD signal is decoded and sent as multichannel PCM or is sent out as two channel DSD.

Network issues can really take the fun out of setting up new equipment. Enjoy your new setup and research. What is the TV model in use here? There are settings to consider when trying to get multichannel PCM output over eARC.

I've got a LG OLED, 65 inch C3. I've got my Nucleus in another room connected to the house router, and its connected via ethernet to my Mac (in another room). I've connected HDMI from the Nucleus to a Google 4K streamer thingy. I'm not sure if its doing anything. I read somewhere that it needs to be connected to a HDMI capable device.
I've downloaded HQPlayer but I haven't got around to setting it up yet and I'm a bit nervous after reading some initial setup stuff. Its irritating when the instructions don't seem to match what I'm seeing.
I've had a few little hiccups - like tonight, setting up a new iPad and that seemed to throw everything out of whack. But its up and going again.
I've turned off the telly lately and just find myself listening to music like I did when I was a teen back in the early 80's. Loving it.
