Hi,
Ever since changing my WiFi/broadband provider last month I’ve been unable to use Alexa on Sonos One.
I finally got round to doing a fresh disabling of everything, factory reset and re-linking of accounts. Sonos Voice Control works fine. Alexa will operate the speaker if I make a voice command through the Alexa App, but if I try to speak to the One speaker directly it does not respond to the “Alexa” wake word command.
The skill is enabled in the Alexa app, it recognises the speaker and can communicate with them to turn on music. I’m guessing this is a bug and I’m sure what else to do.
