Roam 2 airplay and bluetooth grouping issue

That suggests wifi interference of some type. I use Bluetooth or AirPlay 2 quite a bit to a Sonos One, which the signal then gets passed on to my PLAY:1s, and while I haven’t done it today, it’s always worked flawlessly. 

I’d read the linked FAQ, and apply any fixes that might be helpful, and if nothing works, I would recommend that you submit a system diagnostic within 10 minutes of experiencing this problem, and call Sonos Support to discuss it. Don’t post the resulting diagnostic number here, Sonos’ lawyers get sensitive about GDPR, I suspect.

There may be information included in the diagnostic that will help Sonos pinpoint the issue and help you find a solution.

When you speak directly to the Support staff, they have tools at their disposal that will allow them to give you advice specific to your network and Sonos system.

It might be a sequence issue. Start the Bluetooth stream to your Roam 2 first, and then group in the other rooms. 
 

Okay, the problem was that the roam was not the group coordinator. When it is the group coordinator, Bluetooth and airplay content is played across the system. However it seems like the group coordinator keeps defaulting back to the play:1. So every time I have to go back into the Sonos app and reset it.

 Does anyone have ideas for making the roam the default group coordinator always?

Short answer: no, not me, but there may be others able to answer. But: does the group coordinator have anything to do with room names and alphabetical order? 

For Airplay playback, you could check under Settings > General Settings > Airplay > to ensure the option is enabled to Group Non-Airplay products.

Usually when streaming the Group coordinator will be the speaker/Room you first select in the app to add the other Rooms to.

No clue if that applies to Airplay or Bluetooth though.

How to Airplay or Bluetooth (BT) with Sonos and extend to other Sonos speakers *

7. Tap the speaker iCon at the bottom in “Now Playing”
8. Select other speakers to play along
9. Tap apply
10. The speaker selected in #4 is the “Group Coordinator”. **
11. You can add/deselect any Sonos speaker except the “Group Coordinator”

Bluetooth (BT) Example:

 * Both Airplay and BT used in the above manner require a stable network and adequate Wi-Fi signal. As such interruptions (drops) may occur due to internal and/or external interference.
