AirPlay works fine on both devices.
If I try to play music on the Sonos App with Apple Music, the Era100 works perfectly (I also get the Lossless resolution symbol). But if I try to play with the Arc, I get a message saying that “it was not possible to play the selected song, retry” and skips to the next song (and get the same message again).
How can I solve this? I really wanted to make use of the Dolby Atmos feature.
Have you rebooted the Arc? Or checked for updates in the Sonos controller? I’m also wondering about the potential of wifi interference , although if you’re able to use AirPlay 2 to the Arc, that may not be as substantial a worry.
However, if doing those things don’t help, I would recommend that you submit a system diagnostic within 10 minutes of experiencing this problem, and call Sonos Support to discuss it. But don’t post the resulting diagnostic number here, they get sensitive about GDPR.
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.
