Hello,
I’m having the same problem (with the same setup) that this user posted about in 2019:
I’ve rebooted everything, and then followed the advice given to the earlier poster by Jesus Rodriguez:
Remove the power cable from the Rendu and the DAC.
Connect the power cable to the DAC and power it on.
Connect the power cable to the Rendu.
Go to Apps / DAC Diagnostics and confirm the DAC is present.
Go to Roon / Settings / Audio and enable the Rendu.
This sequence solved the problem with the earlier user, but doesn’t seem to work for me - after two attempts. The Ultrarendu still doesn’t appear under Roon / Settings / Audio.
The connections have been working fine for several years, but I had to send my Pure Audio DAC back to them for a repair (there was some noise, apparently due to a ground that had come loose). Now I’ve reattached the repaired DAC, and I can’t get things to work.
I had an ultraRendu for a while, which was great while it lasted. But it died. No warning. I think those things are a bit flakey from a QC point of view TBH. I bought a Lumin T2. Problem solved.
Try going to sonicorbiter.com, click on the device to manage, then Apps > Audio App switcher and make sure RoonReady is active.Then go to Settings and click Save Changes (even if you did not change anything). This frequently did it for me.
Check your ultrarendu sd card is up to date (Apps > Software Manager > Update).
Remember that the DAC must be on before you reboot the ultrarendu. A couple of reboots are sometimes necessary.
The SD card has to be ordered snail mail if it is corrupted. There is no user reload function with SD card loader function . I would talk to Andrew at SGC. He has talked me through several i5 and ultraRendu issues in the past.

I would likely guess the storm fried the SD card.
I had that happen twice and only solution is to buy a new card from them.
One reason I sold it and moved to the Lumin T2 as per @Rockhound
Core runs upstairs in a Nucleus. It finds an Ayre QX-5 Twenty endpoint upstairs that’s connected via ethernet, but it doesn’t find an ultraRendu downstairs that’s on a Google MESH network. I confirmed the network is functioning, I powered up the DAC then powered up the ultraRendu, I power cycled the Nucleus. When I ran core in a Mac Mini I recall it created two zones, upstairs and downstairs, but core is showing only the Ayre and slots for two HDMI devices, one of which I filled with a Bryston SP3 processor. Roon plays with either the Ayer or SP3 upstairs. How do I get Roon to find the ultraRendu downstairs?
I didn’t see it listed at sonic orbiter, but when core ran in the Mini downstairs it found both the ultraRendu and the Ayre, the ultraRendu in the downstairs zone, Ayre in the upstairs zone.
Just as an experiment, I’d move the ultraRendu upstairs and plug it into ethernet and see what happens. That should let you know if there’s something going on with your Google Mesh.
I brought up Roon on the Mini downstairs, and it found the Ayre QX-5 Twenty and Bryston SP3 upstairs, an existence proof that the MESH network is functioning. I also downloaded Qobuz to the Mini, selected the Ayre QB-9 DAC connected to the Mini via UBS, and the sound is excellent. If I can accomplish the same thing with Roon running on the Mini, I’ll be a happy camper. The ultraRendu and LPS 1.2 may become superfluous, but I’ll try them upstairs with a direct Ethernet connection.
I moved the ultraRendu upstairs and connected it to the Ethernet switch and to the Ayre QX-5 Twenty via USB. Roon core in the Nucleus found it. I enabled it selected it to play, The sound is quit good, but not the superb sound of Ethernet direct to the Ayre. Tomorrow I plan the move the ultraRendu back downstairs and replace the Google mesh network with an Eero network. I hope that might work, but I’m skeptical.
