Google Assistant not showing devices in Sonos App

Today’s new message fails:
From Google Assistant:
“Sorry, I couldn’t reach Sonos.”

and

“Sorry, it looks like Sonos is unavailable right now.”

I’ve tried deleting the speakers from Google Home, readding them, uninstalling both GA and Sonos, deleting all services and readding and searching this forum.  

Also, regardless of what room/speaker I tell it to play back on, I get the errors.  Most likely because in setup I see no rooms/speakers when adding Google Assistant to Sonos? 

Same issue for me. It was working last night and now this morning Google Assistant cannot ser the Sonos system. I unlinked the account and when I attempted to link them again using the Sonos SSO service, it appears that google assistant just can’t connect.

Sonos - it looks like some sort of change overnight has caused this issue.

Same problem here.

In the Sonos App (ios iphone xs) I click Settings > Services and add Voice Service. Click Google assistant.

The assistant app is opened and after some time, it's ready. I click on Ready in the Sonos app, but nothing changed, no Voice Service added. Seems really bad there is no feedback at all. Drives you nuts.

Another thing I just noticed is that if I go into the Google Home App and look in Accounts, Sonos does not show up and there’s no way to add it? It’s also not found in connected apps?

Well, I can now get Alexa to play SiriusXM on my Sonos, but clearly she can’t play any Google Playlists.  And I only installed Alexa to see if it would work.  

Ultimately, this is clearly a Google/Sonos issue.  I hate that we have Sonos in nearly every room and can’t get the most out of it. 
 

Oh and this morning I also tried creating a new Google Account for the express purpose of using it for Sonos and I still got the same errors when trying to play Google Playlists or SiriusXM. 

Not sure what’s left to do?

What (& how many) 'voice assistant' Sonos speakers do you have? ...and what is your default music subscription service that you have installed in both your Google Home and Sonos App? Do you have just the one Google Home and have you ensured that your default country location is the same in both your Sonos online profile and your Google Location settings?

Thanks for the response Ken,

None of my Sonos have the voice assistant built in, they’re all from the generation before that. I didn’t think that was required? If it is, then I’m going to feel pretty silly. lol

Default Music subscription is Google Play Music.

And just double checked and both are set correctly to U.S.

And a new strange occurence, if I use the Sonos App and play something from my Google Play Music playlists or from SiriusXM, Google can pause it or even skip to the next track, but that’s it.  If I tell it to play SiriusXM Lithium it still says, “Sorry, it looks like SiriusXM isn’t currently supported on the Library (or whatever room I try).”

Yes the voice services will still provide the option to skip, pause, mute etc. The Sonos Skill/Device is what provides the playback commands. I’m not sure if this works without a Sonos speaker that has voice services, but I think it might. Perhaps someone else here can confirm or refute that matter.

I would perhaps try this … 

Remove the Sonos device in the google home or assistant App. Give it a few moments and ensure that all your Sonos speakers disappear from the Home. (Ensure you only have the one Google Home). 

Next close (slide off screen) and re-open your Apps to refresh them. 

Then having checked your speakers were removed, reinstall the Sonos Skill/Device and ensure each speaker is placed in a chosen room in your Home… the speakers will default to their own rooms but you can move them if necessary.

Also note for this to work the Google Play Music Service must be a ‘paid subscription’ service … free services do not work.

When you have reinstalled the speakers, check that your Google Play Music is set as the default music service and ensure it’s login credentials are the same as your GPM service in the Sonos App.

When playing you also must include the Sonos Room Name in your voice instruction to the Google Asistant. 

Hope that assists to get you up and running with Google.

Well that could be my problem getting Google to play my playlists from google music, since my account is a free one. I thought I’d read it works with free accounts too.  Damn.

Still not sure why SiriusXM won’t work as I do have a paid account there. 

And I’ve deleted the speakers from google home/assistant multiple times and heck even unplugged and readded them into Sonos all with no luck.  

I broke down and emailed a service ticket with the diagnostics from the app as well.
