Downgrading is not supported as I mentioned in my previous message.
Just to confirm, you used the Macbook pro in “Core” mode and not “Remote” mode correct? As in when the “Choose your Core” screen appeared, you selected “Use this PC” and not selected the previous existing ROCK setup?
If this is the case, I would next take a look at the network. We have often seen managed switches such as yours need more advanced settings to work properly. Would you by any chance have an un-managed switch which you can try connecting your ROCK and a few Sonos endpoints to and verify if that is stable?
We only show the Sonos devices we have tested in the lab under “Roon Tested”. As of the time of writing this message, the Sonos devices which are Roon tested are:
- Zoneplayer 80/100
What’s strange is that the Kontor speaker has what appears to be the artwork for the Play:5 but is showing up in Other Network Devices. If you remove the Kontor from the network, does that change any behavior for the other zones?
