I see that a lot of people here and on other forums have problems with activating Google Assistant on Sonos. When I first setup my system there was no problem adding it to Sonos Roam. But after some problems where I had to reset my system Google Assistant couldn’t find Sonos Roam again when I tried to add it.
This is how I managed to add it back again.
- Open Google Home on your phone (I run iOS, might be different on an Android).
- Click Settings.
- Scroll down to the bottom and click Works with Google.
- Click Sonos, and unlink.
- Go to the Sonos app and add Google Assistant as a voice assistant.
Hopefully everything works for you now.
