Hi @Steven_Hecht,
Thanks for your patience so far! After another fresh diagnostic review, we can see:
The Office opticalRendu is completely invisible to Roon. The logs show only one opticalRendu ever appearing — the Living Room one at 192.168.0.yy. The Office opticalRendu never shows up at all. This means it’s either:
- Not getting power
- Not connected to the network (bad ethernet cable, or the port on the router it's plugged into was damaged in the power surge)
- Damaged by the power surge itself
We also see some errors around the system of the PC’s system output. The logs show a repeating error: raat.dat:base.lua failed: Result[Status=InvalidCodeSignature]. This means the Roon app on your Windows 11 PC is corrupted. This is what’s preventing the PC’s own audio output from working, but this is secondary, your main goal is restoring the Office zone via the opticalRendu.
The SonicTransporter runs as a standalone Linux device on your network, not “inside” your Windows PC, it’s a separate small computer box. Here’s how:
To shut it down:
- Open a web browser on any device on your network
- Type
http://192.168.0.172 in the address bar and press Enter
- You should see the sonicTransporter web interface
- Look for a Power or Shutdown button (usually under a Settings or System menu)
- Alternatively: it is safe to simply unplug its power cable since it's a music server (not a database that writes constantly)

These OpticalRendus have no on/off switches. There are 3 cables in back. How do I tell which?

The Sonore opticalRendu has these three connections:
- Optical (fiber) input — a small square port, usually with a plastic dust cap. This carries the network signal via fiber.
- USB output — a standard USB-A port. This is the cable that goes to your Denafrips Ares II DAC.
- Power input — a small round barrel connector (DC power supply).
To power cycle it, you unplug and replug the
power cable (the round one). There is no on/off switch.
This is the core problem. The Office opticalRendu is simply not on the network at all right now. It’s not a software setting issue,
can only see devices that are connected and communicating. Since it doesn’t appear there at all, something physical has failed.
Some additional troubleshooting steps to consider:
- You mentioned USB errors with your printer too. This strongly suggests the USB hub or ports on the PC itself may have been damaged by the power surge. Before touching the opticalRendu:
- Try plugging your printer into a different USB port on the PC
- If the printer still fails on multiple ports, the PC's USB controller may be damaged and needs repair/replacement
- Check the ethernet cable to the Office opticalRendu. Look at the back of your Arris router:
- Find the cable that runs to the office opticalRendu
- Look at the router port it's plugged into — is there a green or amber light blinking on that specific port?
- If no light: the cable or that router port is dead. Try moving it to a different numbered port on the router.
- Power cycle the Office opticalRendu. Unplug its round power cable, wait 30 seconds, plug it back in. Then wait 2 minutes and check

again.
- Check the Denafrips USB input. On the Denafrips Ares II, press the input button until the USB light is lit (not just the monitor light). Then unplug and replug the USB cable between the opticalRendu and the Denafrips.
- If the Office opticalRendu still doesn't appear in [url=http://sonicorbiter.com]sonicorbiter.com[/url] after all the above, the unit itself may have been damaged by the power surge and need replacement. This is the most likely scenario given that it has been completely invisible since the surge.
Regarding the Windows PC “System Output” error: Once the opticalRendu issue is resolved, the Windows Roon app also needs a clean reinstall (as @connor suggested previously). But tackle the hardware problem first, since Roon’s actual job is to send audio to the opticalRendu → Denafrips → Sugden chain, not to play through the PC’s own speakers.
Thank you, Steven!
