I’ve just purchased a new Sonos Roam 2, My Sonos app found it straight away and added it to my system.
I’ve added the Alexa voice control and the Sonos skill to Alexa app also the BBC Sounds Skill.
I’ve added the BBC sounds service to the Sonos app.
When I ask Alexa to play BBC Radio 2 for example it selects BBC World Service West Africa.
I can select Radio 2 from the Sonos app with no problem.
