The Sonos One isn’t a Bluetooth speaker. If you had a Mac, you could play audio to the speaker through AirPlay.

The only Sonos speakers that support Bluetooth are the Move and the Roam.

Thank you for that, I had just assumed I could do more with it!  I’ve bought a Samsung TV and had hoped to connect it to that when it arrives for great sound.  Am I right to think that won’t work either?

Thanks so much for your help.

Unfortunately that won’t work either. Your best option to play TV audio through Sonos speakers is getting a Sonos soundbar like a Beam or Arc.

Dammit, I’ve bought the wrong speaker haven’t I??!!  Thank you for responding - at least you have saved me from hours of trying to work it out!!
