Same exact thing happening to me 

Still no solution here!

Please let me know if you will figure it out. Good luck! 

Same here! The response from the assistant is a bit different now. Feel like something has updated but not in a good way

Also my assistant has changed voice... without any reason.

I wonder what Sonos guys are doing in this very moment reading our messages  

Hello @Ale1911 and welcome to the Sonos Community!

I’d like to apologize to you and the rest of our users in this thread for the delay on my response.

Also my assistant has changed voice... without any reason.

The above makes me believe there’s been a change in your Google Assistant profile settings. You can find instructions by Google on the following page Change Google Assistant settings for both Android and iOS.

I would suggest you to follow the basic troubleshooting steps in our Google Assistant commands not working on Sonos support page.

If by doing so your issue is not resolved, please reach out to our Support team for some live troubleshooting.

I hope this helps.

I started getting the same issue randomly. All signs point to something on Sonos end. No amount of troubleshooting fixes the Google Assistant+Spotify actions. It mentions that it's about to play and then nothing comes out. Removing GA and re-linking it made things even worse - GA never came back on another One speaker. 

Not saying this isn’t a Sonos problem, but the fact this happens on Sonos and (possibly not on Google Mini) is in itself no proof this is a Sonos problem. Google does seem to handle Sonos-sourced requests differently from Google sourced requests. 

If i was the CEO of Sonos I would have already called Google to fix this issue. No one of my friends will never buy Sonos...

Yeah been avoiding removing the link as they mention in other posts that adding GA to a speaker is broken currently

The current answer seems like a bot answer too

I mean it's getting worse alright. I thought that the dust had settled but someone has to get booted for this I'm sure.

Yesterday Sonos released an update. By magic, all issues are gone. Hope the same for you all

Haha was about to write the same! Works for me again, for now

Hi! Unfortunately I am back again.

Spotify not working again.

Same issue: it correctly repeats the command, then nothing happens 

What did Sonos Support say when you called in? 

I could not reach them
