I have an Echo Dot 3rd Gen and Sonos Speaker in most rooms and I have Alexa groups setup to use Sonos as the default speaker.
I have used this with no problems for months with Spotify, Audible and Stitcher all playing by default through Sonos when started via voice control from the Echo Dot.
Now, as of a few days ago, only Spotify plays through the default speaker - Audible and Stitcher play on the Echo Dot. If I specifically ask Alexa to play Audible and Stitcher on a Sonos speaker, they do.
I have re-authorised Spotify, Audible and Stitcher in the Sonos App.
Has anyone else experienced this?

..and now, as if by magic, with no changes made by me, this problem has gone away. Times Radio, Stitcher and Audible (when started using an Alexa skill on an echo dot 3rd gen) play on the default Sonos speaker again
Last night it was still all broken, this morning it all works in every room.
Maybe my echo dots got a software update last night? I can see they are running the latest software (4621172036) but I cannot tell when that was installed and unfortunately I did not note the echo dot software version while the issue was present...so it may have nothing to do it.
Anyway, issue closed.
