Hello everyone,

I just had the same issue and it started to drive me crazy. My BF and I started to check for solutions and we found the one below that has resolved everything. 

Just a little recap first on my specific situation:

I had my Sonos 1 set up with Sonos 1 app. Everything worked fine for months. Then, suddenly, it was bugging and it was not really responding to my commands. 

So, we decided to reset my Sonos 1. After doing that, Sonos told us to download the new SONOS S2 app, which we did. I then linked it to my Google Assistant. That is when I started to have the problem of Google assistant saying : I can't do that here but you can ask me to play it on one of your other devices Sonos

The issue was that I had 2 devices linked to Google Assistant, therefore Google assistant was confused. 

So, the solution that resolved everything has been:

Go to Google assistant app (I didn’t have the GAP so I had to install it to resolve this). 

Then, scroll down to Assistant Devices. I noticed that 2 devices were linked. The first one was when I had Sonos S1 app and the second device was set up with Sonos S2 app. So, I went to the device with Sonos S1 and unlinked it. The device then disappeared from the list. And, only my setting with Sonos S2 app remained. 

Since then, everything works. 

Hope it will help you!

Happy Holidays :)

French American Beat's solution worked for me too.
