Alexa Multiroom music simultaneously on Sonos and Echo devices

I just bought a Sonos Beam after my research failed me and I interpreted Group capability as MRM. Arrived today and love the sound, but contemplating returning it b/c it cannot connect to my echos.

I purchased two Play:1 speakers today.  I’m very disappointed to discover that I can’t group them with my existing Echo devices for multi-room music.  I won’t be buying any more Sonos speakers until this basic capability is added.

Just bought two Sonos Ones and could not believe this.

I plan to return them and get the new echo studio. Supposedly a small step down in audio quality, but worth it for the seamless integration into groups for me! 

I bought the Alexa enabled Sonos Play 5, expecting to have the ability to connect with other Alexa enabled speakers for multi room. Please add support for Sonos speakers to be added to Alexa MRM groups.

Can you tell me how you arrived at this expectation?  Because neither Sonos nor Amazon ever stated you would be able to play Echos and Sonos in sync.  

Not to knock your desire for the feature, but as discussed in this thread, it’s not simply a matter of adding it to the development list and getting it done.

Seems reasonable to assume that if something is supported it would be able to take advantage of the key features. It's like you get a car that says it supports Google maps, but then all you can do is browse maps, not use the routing and traffic functions. An

y rate I've read the whole thread and others and don't agree that there's some prohibitive complexity to it. If other third party jokers can make it work, Sonos can support it. It's a reasonable thread to add a +1 feature request post so they know there is desire for it. Don't need FBs defending status quo. I didn't say anything lame like I deserve my money back or blah blah. Bose also doesn't support it. Just saying as a consumer, I both expect it and want it, regardless.

But your car with google maps likely cannot do everything that Google maps on your phone can do. You’re likely not going to get links into websites, perhaps not get traffic updates, etc, unless you’re tethered to a phone or have some sort internet connection.

I’m not trying to say that expectations and assumptions are not bad in general , but they are not always true and cannot always be met, even though customers may expect and want whatever it is.

I think it was in this thread, but perhaps another, regarding a Polk soundbar that had could participate in Alexa MRM.  The difference between that product and Sonos is that Polk doesn’t have it’s own multiroom system to connect with.  Sure Sonos could build a speaker that only connected to Alexa MRM, or has an Alexa MRM mode, like the Move has a Bluetooth mode.  I don’t think that’s what people are really asking for here.  Are they?

Again, I get the assumption, but I’m not sure how you can expect a feature that was never promised.  I agree that it’s a wanted feature.  I don’t know that I would use it myself personally, but it certainly would be useful to a lot of people.  But that’s not changing the fact that there exist business and technical reasons.why it can’t just be added to the list and knocked out with the next product upgrade.

Hopefully, I’m not coming off as telling people not to ask for features they want.  I’m just trying to add some info so people can understand why the feature doesn’t exist and doesn’t look likely to be exist anytime soon.

I only expect it because it seems reasonable and desirable.

I think people who want the Sonos speakers to interplay with other speakers like my echos or my smart speaker smoke detector or my home theater Panasonic and KEF don't care about the Sonos multi room native protocol. Fortunately on the Bose forum I found a workaround where you just pair or feed an echo input device to each non confirming target and you can treat that pass through as an Amazon mrm.

But this workaround has extra cost, consumes extra space and power, and is extra hassle. Thus the feature request.

IoT. Can't they all just get along? ;)
