Dot won’t play on Playbar but will on others.

Make sure there are no conflicting names for Smart devices in your Alex app. If there aren't any, reproduce the problem, then check the translation in the Alexa app to see if it was correctly heard. If nothing out of the ordinary shows there, I would submit a diagnostic and post the reference number here. That way a Sonos tech can dig deeper.

Thanks for that. Thought it had now started working okay, as, for the first time, when I asked it to play radio on the TV (Playbar’s name), for the first time it said “playing radio on the TV”. Nothing though!

BTW what do mean by checking the translation in the Alexa app? How please?

From the Home screen in the Alexa app, you can Scroll through the "Cards" to see descriptions of your recent Alexa interactions. Viewing these can give you hints as to why the command was not completed.

Ah! Seen those cards but never clicked on “more”. Anyway, there were the commands and before the Dot heard the word “Playback” each time! For TV it apparently heard t.v. Don’t know the significance of the full stops it apparently heard. Anyway will rename Sonos device back to Playbar and rescan on the Alexa app and keep trying with getting it to play with the name Playbar which I prefer.
Now all I need to do is work on my pronunciation which is clearly lacking. Seriously though it’s not that bad as I’ve tried to speak the command very clearly. How the Dot manages with all the English accents I don’t know.
Thanks again for your help. Appreciated.

Ran into problems with my Boston accent a few times. Told it to play The Cars, 'Bye Bye Love' and she though I meant 'The Casbah' by Love.

IMO, unless and until speech recognition improves considerably I foresee the situation where I will very soon give up on it.

I had this issue as well, my understanding of it was that i would say "alexa play the killers on playbar" and alexa misunderstood me and a couple of time started playing something called bar directly on the alexa, i think it was because playbar has the word play in it, it took me a couple of goes to get round it, i renamed my playbar in sonos app to TV and it tried to play through my amazon tv stick so renamed again to den and all seems to be fine. I also had a problem with the Killers new album, would ask to play wonderful wonderful by the killers expecting to play the whole album but no it just played the song called wonderful wonderful on the album named the same
thanks bruce

I accept it’s a relatively new technology but I do wonder that if things do not improve, users will get frustrated and angry with inaccurate or non recognition of speech and the novelty will diminish use.
Remember 3D TV!

Still having problems. Renamed Playbar back to “Playbar”. My Lounge Connect, Playbar and Play 3 in the bedroom are all recognised in the Alexa app. Asked Dot to play radio on Playbar - nothing, despite telling me that radio was playing on Playbar. Then asked it to play radio in lounge via Connect - nothing, although Play 3 no problems. When I unsuccessfully tried Playbar and Lounge to play radio and told the Dot to stop it asked me which I wanted to stop, Lounge or Playbar so it clearly thought both were playing!
Will contact Sonos support I think.
Advice please, if I do email them can I add a diagnostic number to it or should I just wait to be asked for it? As regards diagnosis numbers, do I replicate the problem then immediately generate a diagnostic reference at the moment I have unsuccessfully tried to play to a device from the Echo? Not done this before.
Thanks.
