Unable to turn on/off TV through voice command (chromecast)

Hi 

 

I have a weird issue. For years I have been able to turn on/off my TV through voice command using google assistant on my Sonos One. Suddenly this has stopped working, and the google assistant in Sonos says “Sorry unknown error has occured on [name of my chromecast]” (this error might not be precise, I have translated it from my native language).

 

I am able to for example pause/unpause the chromecast using voice command.

 

If if say the exact same turn on/off command using the Assistant app on my phone the TV turns on/off.

 

I have tried unlinking/removing my assistant both in Google Home app, and in the Sonos. Linked it again, and went through the setup process, but the same error occurs. I have also tried renaming my Chromecast (found that advice in a similar thread), but same result.

 

Both my Sonos One and Chromecast has newest firmware.

 

If i go to https://myactivity.google.com/ and filter on assistant, I can see the command, and here it also says that unknown error has occured.

 

Anyone else experienced this problem, or have any advice on how to debug this?

 

TIA

Try removing Google voice assistant from your Sonos app--then use your phone or other smart speaker. This magically fixed my tv on/off via Sonos Arc function. I don't get to use my Arc microphone anymore for GA, but it wasn't as good at interpreting commands as y phone and Google smart speakers anyway.

Bump - same issue ☹️

 

Until now I hadn't added a voice assistant to Sonos. I added Google Assistant yesterday so I could remove a nearby Google Nest, and my most-used feature - turning the TV on or off - stopped working. It's so strange! Other than that the Google integration seems to be great. This is frustrating and disappointing! Hope it does get fixed although the age of this conversation suggests not... 🫤 I don't want to go back to using the Nest as it often can't hear over the beautiful sound of the Sonos 😅

@Sonos - I’m checking in again after half a year. Any update? Any solution in the making?

 

it is clearly an issue that bugs quite some people. I do know that Sonos and Google are not best friends right now, due to the lawsuit and what not. Obviously, that will not speed up any solution for this. I think we all just expect a solution within a reasonable amount of time. 


This feature worked before and other integrations support the on/off command for a Chromecast (even the free and open source Home Assistant does support it).

 

Hope to get an update or a statement soon!

 

Regards,

Hans

This has been annoying me for months. It used to work, and then it stopped working. 
Finally i found a workaround that works for me. 

When i link sonos in google home app, i now get the option to add the «sonos tv control».
 

I place this in the same room as my tv (which is connected to the sonos beam). I name this controller «TV». I can now say «ok google, turn off TV» and the TV turns off.

I have received a complete set of Sonos Arc + Sub + 2x Era. I have set it up last week and turning on the TV was absolutely fine.

 

After some connection problems i have setup Google Assistant from scratch and now have the exact same problem.

Turn on TV command where from Google Home or Google Assistant app but not from Sonos App.

Any ideas? The work around above results in the same issue.
