Hi Colin,
Looks like I spoke too soon.
I ended up adding in the following ServiceID's into the new AirGroup:
id "urn:schemas-upnp-org:service:GroupRenderingControl:1"
id "urn:schemas-sonos-com:service:Queue:1"
id "urn:schemas-upnp-org:service:AVTransport:1"
id "urn:schemas-upnp-org:service:RenderingControl:1"
id "urn:schemas-tencent-com:service:QPlay:1"
id "urn:schemas-upnp-org:service:GroupManagement:1"
id "urn:schemas-upnp-org:service:ZoneGroupTopology:1"
id "urn:schemas-upnp-org:service:DeviceProperties:1"
id "urn:schemas-upnp-org:service:MusicServices:1"
id "urn:schemas-upnp-org:service:AlarmClock:1"
id "urn:schemas-upnp-org:device:ZonePlayer:1"
id "urn:schemas-upnp-org:service:SystemProperties:1"
id "urn:schemas-upnp-org:service:ContentDirectory:1"
id "urn:schemas-upnp-org:service:ConnectionManager:1"
(NEW) id "urn:smartspeaker-audio:service:SpeakerGroup:1
Out of desperation I also added in the following:
urn:schemas-wifialliance-org:device:WFADevice:1
urn:schemas-wifialliance-org:service:WFAWLANConfig:1
urn:schemas-upnp-org:device:InternetGatewayDevice:1
urn:schemas-upnp-org:service:WANIPConnection:1
urn:schemas-upnp-org:service:WANPPPConnection:1
In the end I was able to add in the Extra Sonos Speakers but only by having them connected to the same WAP as the first Sonos Speaker I setup.
Once they were all installed and setup in the app I re-positioned the 5 x speakers around the site.
Once I had all 5 of the speakers connected I conducted some testing and found that depening on which AP I was connected to changed the amount of speakers I could see in the Sonos Application.
At one end of the site I could see 4 of 5 speakers and at another end of the site I could only see 1 etc.
Is there a setting in the Aruba controller that could have something to do with this?
I currently have Broadcast filtering, Multicast transmission optimization and Dynamic multicast optimization ALL disabled.
Any help would be greatly appreciated.
