Sonos volume dims on all speakers when Alexa is activated

A little bit of background..
I have speakers in different rooms, and have set them up to reflect this. We have an echo dot in the living room, which is connected via the Sonos skill.
I often listen to music in my study while the kids are in the living room.

I began to notice the volume on my speakers started to occasionally dim for no seemingly reason, then would go back to normal a few seconds later. Typically it was worse when the kids were home.

After a lot of troubleshooting, I figured out that Alexa isn't Sonos room aware. This means whenever she is activated (be it on purpose or by accident), she will dim the music on ALL speakers in the house to allow you to hear her.

I have logged a call with Sonos support, who have requested I post on the community forum to explain the problem I've found, while they pass it onto their development team.

The other down-side to having multiple rooms setup is that you have to stipulate 'Alexa - play SONG on SPEAKER'. She also isn't aware of my music library and will only play songs from Amazon. Has anyone else found a way around this?

Denon would suffer from the same problem. It is an Alexa thing, not a Sonos thing. It is supposed to be solved when the "promised for early 2018" Amazon AVS Multi-Room Music SDK finally arrives.

Maybe, overall. it is. But the Connect:Amp doesn't even have voice control. It's not connected to Alexa and dimming the sound on this device is completely pointless. It's as though the Sonos implementation is an all or nothing scenario. As the "all" option means that every speaker goes quiet to wait for a response to a command that it cannot respond to, then it is a poor implementation. What testing did they do before releasing this? It seems that they did little to none. This must have come up if they tested it properly, and that should have been a hard blocker for the development. It's not a multi-room system if they all respond to a command from elsewhere. The definition of multi-room is that each room is independent. What is independent about speakers all responding to a command on a different device 100 yards away? It's another case of a company jumping on a bandwagon without understanding how the customer actually uses the product. It's similar to the online shopping debacle of the late 90's. No company wanted to be the one without an online shop, regardless of how terrible and badly thought out it was. Sonos should have stayed away if the SDK didn't support their brand concept, not shoehorn it in and hope no one complains too much. All they've managed to do is taint their brand.

Yup, same issue here. Super annoying. I am not shocked to see that this is just being blamed on Amazon.

Getting same thing here too (just hooked up Alexa -- using multiple Echos throughout the hosue - to my multiple speakers / Sonos system yesterday)... I thought it was only if I was using Alexa to initiate the request to play music on Amazon music but it happens even if I'm using the Sonos app to initiate the music request from Apple Music. Doesn't matter what speaker or what echo is involved ... it happens everywhere. I'm guessing no fix as of yet - I'm wondering if the Sonos Alexa skill is worth it at this point if you have multiple people in the house.

It has been fixed. See this link on how to configure Alexa groups:

There is a fix. You need to create Alexa Groups in the Alexa app. Put an Echo device and one or more speakers into a group. Only those will 'duck' when you use Alexa through that Alexa device, provided your other speakers are in other groups. In each group set the 'preferred speakers' to be the Sonos speaker(s) that you want to play by default (i.e. without having to name a Sonos room).
