I recently added a Sony SRS-ZR5 to my network. I'm able to cast music directly to it (using both Google Cast and Spotify Connect). However, I am unable to play music from it as part of a group. Music plays from the other speakers, but not the Sony. The group has a Google Home and a Chromecast Audio device (it doesn't work no matter what combination I use to form a group).
Every other casting app I have (TuneIn, Pandora, Pocket Casts, Google Play Music) is able to cast to all speakers in the group without an issue. I have uninstalled and reinstalled the Spotify app, which had no effect.
I appreciate your help with this issue!
We're glad it's working now. If you need anything else, just let us know.
Take care 🙂
