Two SONOS speakers airplay only, two SONOS speakers SONOS only. How to group?

[Bas_Olthoff]

Roon Core Machine

My core machine is a W10 i7 with 32Gb RAM. I usually stream to my ethernet-connected Omnia speaker through its ROON Ready protocol, though this speaker also shows in ROON as available through Airplay and Chromecast.

Networking Gear & Setup Details and connected audio devices

My core is connected to 1Gb ethernet. My Omnia speaker is connected to the same ethernet. My SONOS speakers are connected to dual band wifi, which is implemented as a mesh network through a bunch of TP-Link X90s on top of the LAN.

Audio Endpoints

These are two sets in a single Sonos group of 4 speakers: 2x ONE SL and 2x IKEA Frame. Sonos has them grouped to type (so one group is 2x ONE SL and one group is 2x Frame). Sonos then links the groups and I can play back to all four speakers. This works directly through Sonos and I can also address the four speakers through Airplay as well. It just works: The group is always there as an endpoint in whatever app/software I use to play music.

Description of Issue

I recently tried to use my Sonos speakers as an endpoint in ROON. My SONOS speakers show up in ROON, but only once each. Two speakers show up as “via Sonos streaming” only and two speakers show up as “via AirPlay” only. Because of the different streaming protocols, I can not make a single group with 4 speakers in ROON. This problem is exclusive to ROON: I can boundle the 4 speakers in Airplay (on my iphone) and in Sonos, just not in ROON. Surprisingly, the two speakers that use Airplay are not the same type: One set of ONE SL and Frame uses Airplay streaming and one set ONE SL and Frame uses Sonos. So this is not an issue at the hardware level.

Problem: Please help me connect to all four speakers at the same time in ROON.

I would suggest in the short term to link the Sonos Speakers in the Sonos app and send the music to that group that I hope will then show up

I had to do this for a long time until everything seemed to start working for me again in terms of grouping and Sonos dropping off the network.

Roon still does not unlink the groups if you do it in the Roon app, so it is easier to do on the Sonos app for reliability and not annoying the wife while she is sleeping

speakers living room 2 & 4 have the same IP; same for speakers living room & living room 3

are you sure they are not same sonos-group visible through airplay & sonos?

if you play music from roon to “living room” endpoint, sound is coming out through one or two speakers?

Thanks, that was it. The speakers showing up in ROON were Sonos speaker sets, not the individual speakers. So each set was listed twice, one instance for each streaming service. I have it working now, thanks!
