Grouped room being broken apart by Amazon Alexa

I am having the exact same issue. I deleted the Skill, then "forgot" all the speakers in Alexa, installed the skill, did a search for new devices, then grouped them in the Sonos app and asked Alexa to play an album in one of the grouped rooms. Immediately all the speakers separated.

This started happening to me this morning. Everything was fine yesterday, but now when I pause one Sonos node, it drops that node out of the group and then the group continues playing without it.
Frustrating.

I have the same issue only started in the last couple of days, I have removed the Sonos skill, reinstalled and it still won’t work and only plays on one speaker ignoring the groups set in Sonos, please fix this otherwise Alexa is useless with Sonos

Same here. Been using Sonos on Alexa (mostly) successfully for over a year. Now the group breaks up every time. No luck with disable/enabling the skill. My diagnositic is 94414782.

We don't know all the functionality yet as things seem to be rolling out ahead of time that Sonos hasn't announced. It appears to me Sonos hasn't been able to announce anything until Amazon rolls out their part and appears Amazon now started rolling out their part - so shouldn't be long before Sonos announces their part and what all is happening. Remember Alexa integration is considered BETA so we are going to have times where it is going through a development cycle that things are going to get squirrely!

One thing you can do now though is autogroup. If you setup a room group in the Alexa app with your alexa and then for default speakers pick say 3 different speakers that you always want grouped when you ask that alexa. Now you can tell Alexa to play music (you won't have to give room name anymore) and it will actually create a group with those 3 speakers before playing.

So if your problem is you always have 3 zones grouped together and Alexa is breaking that group. Go into alexa app groups create a group with that alexa device....put those 3 speakers in the default music. Then alexa won't break the group and will actually create the group if it was broken previously.

For more dynamic grouping you can use www.speakerscenes.com to create specific permanent groups in your house that you can then tell Alexa to group on the fly as needed.

I'm also having this issue. Has probably been happening for a month or so I guess. Previously, the way it worked: From within the Sonos app I would group all 6 Sonos Speakers. They would play as a group from the Sonos app as expected. If I asked Alexa to "play music on Den", music would play through all 6 Sonos Speakers (since Den was one of the Sonos Speakers that had been grouped via the Sonos app). Now, this does not work. Now, although I have the same 6 Sonos Speakers grouped from within the Sonos app, when I ask Alexa to "play music on Den", not only does she only play music on Den, but she breaks up the Sonos grouping. I visually see the group break up from within the Sonos app when she begins to play music on Den. I've already tried multiple iterations of disabling the Alexa Sonos skill, removing and rediscovering the Sonos Speakers, etc... No luck.

My diagnostics number is 828179666.

Continuing to research and see this relatively new post: https://en.community.sonos.com/announcements-228985/sonos-now-playing-with-alexa-groups-6817588. Although this does seem to work, it also seems to have some bugs. I'll head over to that thread and discuss further. But in my opinion, Sonos and Amazon have finally moved past the old way of grouping Sonos Speakers. Thank you (finally)!

I've tried to explain in this post: https://en.community.sonos.com/amazon-alexa-and-sonos-229102/an-overview-and-explanation-of-the-new-support-for-alexa-grouping-6817788/index1.html#post16298346

This is a cool workaround and got me at least back to my old functionality, if not a bit more. It's still a bit finicky (I noticed that if you're already playing music somewhere you have to stop that music first as it doesn't like to regroup while playing) but I think this is a good workaround until they actually bring this integration out of beta (where it's been for ... 2 years plus?) Thanks, Chris!
