· Telus Router NH20A there is a switch 20 port and an unmanaged switch that is Trendnet 4 port that is used for all the audio pieces - Ethernet hard wired system - Intel Nuc with Roon Rock, sooner Optical rendu (running squeezelite bridge,) and the Naim NDS
I think the next step here is to enable some diagnostics on your account so our technical staff can get some more insight into what’s going on here.
However, before I enable this feature, I’d like to ask for your help ensuring we gather the right information.
First, can you please reproduce the issue once more and note the time at which the error occurs. Then respond here with that time, and I’ll make sure we review the diagnostics related to that timestamp.
And at 11:39 after attempting to get it working by choosing play a few times where it didn’t work, it then after a pause of a minute or two now it works properly. Sometimes it doesn’t reset for an hour or two or longer even after restarting the optical rendu the intel NUC with Roon and the streamer Naim NDS. In case this helps
Thanks for the timestamps! I believe we have a fresh fix in the latest version of Roon that should help you with your issues. If you could please update your server and remotes to the latest version, then let me know if you still run into issues.
Thank you for providing those timestamps and the extra context!
Looking at the diagnostic logs from your server around that time, we can see exactly what is causing the skipping. Your endpoint (the OpticalRendu) is momentarily but completely dropping its connection to the Roon Server. Roon waits for data, eventually times out (no data received for >10000ms. Killing connection), and as the endpoint disconnects, playback halts and Roon skips forward.
We noticed in the logs that you are currently running the OpticalRendu using the Squeezelite bridge mode. Since Sonore devices are fully certified, have you tried switching the OpticalRendu’s active output mode to Roon Ready?
Using the native Roon Ready (RAAT) protocol is generally much more stable and robust than bridging via Squeezelite, and it may completely resolve these intermittent drops.
To test this out:
Go to your Sonicorbiter Optical Rendu web interface
Navigate to Settings > App Switcher.
Select Roon Ready instead of Squeezelite.
Back in Roon, make sure Squeezebox support is disabled (Settings > Setup), and then enable your OpticalRendu under the Roon Ready section in Settings > Audio.
Let us know if you can give this a try, and if the skipping behavior persists while using the native Roon Ready mode!
I appreciate your analysis and suggestions. These detailed logs seem very helpful.
I’d like to give this a try but my Naim NDS doesn’t have a USB input which I believe is required to use the Rendu in Roon Ready mode. I use the squeezelite bridge mode to connect in UPnP mode which is optimal for the NDS. It does have optical and Coaxial inputs. However I also don’t have a USB/SPIP converter device and the Optical Rendu doesn’t have optical output.
Without the above, I don’t think Roon will connect to my NDS.
I Guess it raises the question as to why the sonic optical Rendu is dropping the connection to Roon in the first place. I’ve heard that giving the Roon Rock a fixed IP helps improve stability in some applications. Any chance this could improve connectivity? Appreciate instructions on how to do that if it’s a reasonable option.
Giving your ROCK a static (fixed) IP is definitely a best practice move. It prevents the Naim or the Rendu from losing the server if the router decides to reassign addresses. Let me know if you need help or troubleshooting steps on how to set a static IP for your ROCK.
And if you haven’t yet, for a few hours, try plugging the ROCK, the Optical Rendu, and the NDS all into that same Trendnet 4-port switch.
Any guidance on best practices for static IP is appreciated:) I’m a rookie at IP address assignment.
I do have my home LAN connected to the trend net switch then from there it feeds the Optical Rendu, the Nuc/Roon core/Naim NDS. Prior its router, switch and Ethernet cable to the hifi space wall jack.
Ah, that makes perfect sense! Thank you for clarifying your hardware setup. Without a USB input on the Naim NDS, you are absolutely right—you cannot use the native Roon Ready output of the OpticalRendu and must rely on the Squeezelite-to-UPnP bridge.
Regarding your question about assigning a fixed (static) IP address to your Roon ROCK:
To be completely candid, while setting a static IP for a server is generally good network housekeeping, it is highly unlikely to fix this specific dropout issue. Devices typically hold their DHCP (dynamic) IP leases for 24 hours or more. Even when a lease renews, it is designed to be seamless and does not interrupt active network traffic. Since your connection is dropping frequently and right in the middle of active playback, the root cause is almost certainly related to how the bridging software handles the audio stream, or how the network switches route that specific traffic.
That being said, setting a static IP certainly won’t hurt, and it is easy to do!
How to set a Static IP on Roon ROCK:
Open a web browser on any device connected to your network and type in the current IP address of your ROCK. This opens the ROCK Web Administration Interface.
Scroll down to the Network Setup section and click the down arrow next to “Ethernet”.
Change the IP Setup from DHCP to Static IP.
Enter your desired IP Address (ensure it is outside your router’s normal DHCP assignable pool so another device doesn’t try to claim it), Netmask (usually 255.255.255.0), Gateway (your router’s IP), and DNS Server (e.g., 8.8.8.8 or your router’s IP).
Click Save.
The real suspect: Network Topology Since UPnP and bridging software rely heavily on consistent multicast network traffic, the network switches you mentioned are the prime suspects. Unmanaged switches (like your 4-port Trendnet) or complex setups with 20-port switches can sometimes struggle to properly route the continuous data stream Roon requires for bridged endpoints.
Would it be possible for you to temporarily bypass both switches and plug the OpticalRendu and the Intel NUC directly into the back of your Telus router? This is the best way to determine if a switch is choking the stream.
Let us know if you decide to set the static IP, and if simplifying the network path makes any difference in stability!
