I recently installed a Nucleus+ and configured it to work with my Control4 system. I have 10 Sonos devices that are visible to Roon. I am able to play music through the Control4 Roon driver when it is for one Sonos device at a time. However, when I attempt to add a room to the currently playing zone through the Control4 “zones” interface (the icon at the bottom right of the C4 touch screen interface), playback stops and crashes in all grouped Sonos zones. I cannot restart playback without turning off each grouped zone and then playing a single zone again. Grouping works fine through the Roon app, but I can never get it to work through Control4. Details of my setup are below.
There are 11 audio devices in the house. One is a Pro-Ject DAC connected via USB to the Nucleus+. The other 10 are all Sonos units. The zone grouping connections seem to be correct – all the Sonos devices are grouped together, and the DAC is grouped separately. Screenshots are attached of these two configuration pages.
I have one copy of the Sonos endorsed driver installed in Control4 for each of the Sonos units, and one copy of the Roon zone driver installed for each of the Sonos units as well. The Sonos drivers are connected to Audio endpoint 1 in each room, while the Roon zone drivers are connected to Audio endpoint 2. Screenshots are attached of the Roon zone connections and the Sonos zone connections, in case that helps.
Thanks for your advice.
