Beam 2 no longer plays music

Will it play music if you instigate from the app? 

No, and I have looked at the settings in Music and in the Sonos app. I have disconnected the beam reconnected and the same with the router!

Assuming the Beam has access to the internet, that’s very odd behaviour. Are you using a wired or WiFi connection? If WiFi, have you accidentally turned off the Beam’s WiFi connection? 
 

It may be worth checking with Sonos support to see if they can detect any issues. 

Thanks yes it is on wifi. But also attached to a Sony TV and a Fire stick.  The tv sound is fine through the Beam.

Two different input methods. The Beam communicates with the TV through the HDMI-ARC connection, the BBC radio communicates through the Internet, be it WiFi or cable wired. 

Can't help with the voice stuff but maybe a basic restart would help.

Power down all Sonos, reboot router and controller, power up the Sonos. 

Thanks.  I have done all that, but I guess it is worth another try.

Is the Alexa side set right?

As far as I can tell.  It seems to be.

Thought I woud try the community first.  Next thing I will do is to contact support!

Support had me uninstall and reinstall Amazon Music and the Alexa app aafter signing out of all Amaxon accounts. After reinstalling,  I also disabled tthe sonos skill and re-enabled it in Alexa.  After all this now my Beam 2 plays my music via Amazon music, or radio via BBC Sounds!  Yay!  Support sorted me out thanks.
