Hello @Arock42, welcome to Sonos Community!
I am currently able to listen using Bluetooth to both my Sonos Roam and Sonos Era 300 from my smartphone.
With what phone are you facing this issue? Do you have any other device capable of pairing via Bluetooth with your Sonos Roam to test?
Maybe reboot your Sonos Roam and phone, if you haven’t done that already.
For me, after completing the pairing, it took 2-3 seconds for the Sonos Roam to start playing audio from my phone. Since I’ve been using Bluetooth connection with my PC as well, I’ve found out that adjusting the volume via the hardware buttons of the Sonos Roam gets the audio output a bit faster.
If you are getting no audio even after the reboot, I would suggest reaching out to our Sonos Support for further troubleshooting.
I hope this helps.
