Roon does not see my Ultra as an end point

Set up my brand new Ultra yesterday. Set up was easy and I enjoyed several hours of exploring and using the different functions of the unit. All went very well except for using rooN as the input. rooN does not see the Ultra as a “zone” (endpoint).

The Ultra is configured as a DAC with fixed volume playing into my analog preamp. Input is hard wired Ethernet connected to my Mac mini running rooN core. The Ultra does not appear as a “selectable” zone. I’m an experienced rooN user. Prior to the Ultra setup was;

Mac mini - network - Oppo 205 LAN input
Mac mini - network - SOtM 200 LAN input - USB output - Oppo 205 USB input

Both the above connections worked flawlessly. I’m at a loss why rooN does not see Ultra. 😳 Any help would be greatly appreciated. Tnx.

Welcome.

I hate to suggest it as you are not a Roon Rookie, but have you tried restarting Roon since introducing the ultra?
I only mention this as Wiim very (very) recently added roon to the amp ultra and suggested this if not found, so may be similar for your (non-amp) ultra.

Thanks for the suggestion. I had not. Will try later today.

Just reread your first post where you say your Ultra is hard wired connected to your Mac Mini - shouldn’t it be connected to your router? I doubt if the Ultra or Mac support peer to peer networking in that manner.
 
Sorry, I stated incorrectly. The Mac is connected to the router in the computer room. The router is connected to the network switch located in the media room.

Possibly a firewall issue. I have no idea which ports Roon uses, but they (obviously) need to be open.
 
AI sez:

To ensure Roon functions correctly, several TCP and UDP ports need to be open in your firewall and router's port forwarding settings. These ports are necessary for communication between the Roon Core, remote devices, and the Roon ARC application.

Key Ports:
  • TCP: 9330-9339, 30000-30010
  • UDP: 9003, 32768-65535
  • TCP: 55000 (for Roon ARC, can be customized)
Other Ports to Consider:
  • TCP 9100-9200: These ports are often mentioned in connection with Roon Bridge and general Roon communication.

  • UDP 43285 and 45029: Some users have reported needing these open, particularly when using certain network devices.

  • TCP Port 9200: This port is mentioned as a destination port for Roon on the WAN.

  • TCP Port 53: For DNS (Domain Name System) lookups, crucial for discovering and connecting to services.

  • TCP Port 139 or 445: For SMB (Server Message Block) file sharing, which may be used by Roon.
Explanation:
  • Roon Server: The core Roon software that manages your music library and playback.
  • Roon Remote: The app used to control Roon on your devices.
  • Roon ARC: The mobile app for remote access to your Roon library.

  • UPnP/NAT-PMP: These are protocols that routers use to automatically configure port forwarding. If they are not working, you may need to manually configure port forwarding.
Troubleshooting:
  • If you are having trouble connecting, ensure UPnP is enabled on your router or manually configure port forwarding with the correct IP address and port numbers, according to Roon's documentation.

  • If using multiple routers, ensure port forwarding is configured on each router in the chain, according to community forums.

  • If you are using a firewall (like firewalld or ufw), make sure to allow the necessary TCP and UDP traffic.

  • For more complex setups, you may need to allow multicast and broadcast communication in your firewall.
 
Never had either problem with the router going to the Oppo 205 Ethernet input or the SOtM Ethernet input. I’ll try changing around some ports on my eight input switch but I doubt that will solve the issue.
