I am having a problem with my brand new Onkyo TX-NR686 that is advertised as "Works with Sonos" actually connecting to my new Sonos Connect for the purpose of having the receiver turn on and the input switched so the Sonos Connect input. I have updated the Onkyo to the latest firmware. All my Sonos speakers and connects are at the latest 10.0 update. I connect the Sonos Connect to the CD analog inputs on the Onkyo like the instructional video specifies. I go through all the correct settings on the Onkyo as per the instructions. The Onkyo and Connect are on the same network and subnet. I have verified that I can see both units on my network. The Sonos system works fine and I can even manually turn on the Onkyo and change the input to CD and the Connect music comes through fine.
However the reason I bought it and the Connect is because of the "Works with Sonos" integration feature that automatically is supposed to turn on the Onkyo receiver and change inputs to the Sonos input when it detects music on that input.
I am a Network Administrator have have a Meraki Mesh WiFi system and an MX Meraki security appliance. I have two VLAN's and had to enable Spanning Tree settings on all may switches to be able to have multiple Sonos Connect:Amps connected to ethernet. My network works great, Sonos works great, the Onkyo connects to the internet and I can stream Spotify, Tidal, and Pandora on it. But it cannot find my Connect during setup. Both are connected wired to the same switch. I have tried putting both on WiFi and have even ran two long 100 ft ethernet cables directly to the router thus bypassing the managed switches to no avail.
Could the Meraki MX65 security appliance router be the issue? I have no way of testing on a different router. I have read elsewhere where some others have had similar problems after the Sonos 10.0 update. However neither Onkyo or Sonos have been able to verify if that is in fact an issue. They cannot figure it out after multiple calls to each.
If someone on here is running and Onkyo and has the "Works with Sonos" working after Sonos update 10.0 please let me know so I can exclude the software upgrade as the issue.
