Multiroom audio Chromecast

I am trying to use "Chromecast audio" devices (the hockeypuck shaped audio only device) to provide music ot an area.  One of the features that is suppose to work is multi-room support allowing streaming to many devices at once.   I was able to get the Chromecasts setup and audio streaming to a single device, however it will not work when you attempt to group the devices.  Any ideas what needs to be configured to have this work?  I don't see alot of documentation on chromecast audio

Add this id to your Googlecast AirGroup service: "_googlezone._tcp"

Re: Multiroom audio Chromecast

I tried this but still, no luck.  What should I have to restart before I test? The chromecasts the computer, the controller?   Also where did you find that entry?  is there some website that updates and lists  all the possible services?   Great find!

Re: Multiroom audio Chromecast

Did you delete the devices from the user-table?



I found the service ID in a packet capture.

Re: Multiroom audio Chromecast

I had deleted them and still no luck.  The music plays on a single chromecast,  even if you choose a group.  I have tried it from android and iOS. It still could be a  chromecast software thing, but I dont have a great place to test it currently, maybe I will take it home to see if it works properly at home.  Coult there be another air-groups setting I am missing?
