Crestron + Roon Nucleus == problems

[noris]

Hello @Maxim_Balitskiy,

Thanks for contacting support regarding this issue. Let me try to address a few of your points:

• I noticed that you are usng a CP3N processor, which contains a dedicated control subnet port. In our experience, we have noticed that processors with dedicated Control Subnet ports (CP3N/AV3) sometimes have issues establishing proper communication with the module. We are investigating possible workarounds for this, but none have been released at the moment and the internal NAT in processors with Control Subnets seems to cause issues with Roon operating properly.

• You mentioned that you have all your devices connected to an Ubiquiti switch. We have seen that the “flow control” setting on these switches sometimes need to be enabled for Roon to operate properly, please take a look at these threads:

Not every switch is the same, not every protocol stream the same [Flow control on switch solved dropouts]

Just to share my experience on CAS streaming system troubleshooting experience on network related issue, where users may experience below problems : your mobile app can not locate your server stuttering sound output when streaming from a Roon server to a Roon bridge such as microRendu etc above may happens consistently with a particular switch / network, or randomly with the same switch. the problem often happen with HQP / NAA only, switch back to RAAT and problem gone Anyway if you swap w…

Roon 1.2 plays DSD 128, Roon 1.3 version 196 doesn't [Solved, managed switch flow control]

Hi, I got some advancement in my investigation thanks to a fine tuning on my Cisco switch. I’ve reloaded my RPI3 with a Unbuntu server 16.04 armv7 on which I installed Roon 1.3 armv7. 192Khz not playing by default. If I activate on the Cisco switch (SL M2008) the option “Flow control” on the port connected to my router, 192Khz files are working. Great! The “Flow control” on the LAN port connected to the RPI3 does not seem to change anything. The JumboFrame option has no effect. I’m still no…

• If you have any other firewall applications on your Ubiquiti switch or Windows 7 PC, I would try temporarily disabling them as well to see if performance improves.

• Since the “Explore” menu is not loading properly at times, this could indicate that either that there is something blocking proper communication to the Roon module or that the module wasn’t able to establish successful communication with the Nucleus. I would perform a “Recompile-All” in your SIMPL program and try uploading the module again to the processor.

• Yes, resetting the program will cause Roon to stop communicating with the module. I am noticing some strange behavior when just pressing “Reset Program” in debugger as you did in the last video and I have asked QA to take a closer look at this behavior, I appreciate your patience while this request reaches their queue.

Please let me know if any of my above suggestions help and I will be sure to let you know once I hear back from QA.

Thanks,
Noris
