Description of Issue

Trying to connect to devices via Sonos streaming but am only seeing AirPlay. They were previously connected via Sonos Streaming and working fine, but yesterday stopped when I added a new room with Ikea Symfonisk Sonos Frames x2. Over the past four months using Roon I would have this come up occasionally, but a reboot of the Roon Core would always fix it. Now the reboot doesn’t fix it and all of my speakers that were previously set up in Roon via Sonos Streaming are only available by AirPlay.

All speakers work normally via the Sonos app.

Any help would be appreciated. Thanks!!

Hi @JordanKo,

Thank you for your patience while we worked through the queue to reach your inquiry.

Do you have any firewalls in your setup?

Since installing the new Sonos speakers seems to have been the triggering factor above, we’re curious if connecting them to a different access point changes the situation.

When you add new grouped devices to a SonosNET configuration, SonosNET will use existing, online speakers in the setup to forward traffic to the discovered devices. This behavior will differ depending on whether the device is wired (ethernet) or connected via WiFi.

Depending on the specific configuration, this can cause multicast traffic to route to the wrong place or bombard certain devices with too much traffic.

How do your access points configure into the schematic you’ve outlined above? I’m assuming Room 1, Room 2, Room 3, and Room 4, and Room 5? all have either a router or one of your five access points?

Where is the TP-Link switch in the network schematic above? What about your RoonServer machine?

Lastly, a differentiating factor between the AirPlay and Sonos protocols is the use of UPnP in the router firmware. What is the make/model of your router? Do you have the most recent firmware, and is UPnP installed? Do you have any issues with Roon ARC autoconfiguration (this also uses UPnP)?
