I'm using Apple Music with a Sonos setup consisting of Arc + Sub + two Era 300 speakers.
When I play the following album, playback consistently halts mid-track, and the Sonos system becomes completely unresponsive—as if it's frozen. After a short while, it recovers as though it had rebooted.

(Tchaikovsky: The Sleeping Beauty; Children's Album; Piano Sonata, Op. 80; Theme and Variations, Op. 19/6 – performed by Danil Trifonov)
If you're using Apple Music, could you try playing this album from the beginning and see if the issue occurs?(not via AirPlay, but directly from Sonos App) In my case, the problem happens 100% of the time, although the timing varies. It usually doesn't take long to reproduce.
There have been reports in this community of similar issues with Sonos + Apple Music—such as tracks skipping, audio dropouts, or playback stopping unexpectedly—and I believe this may be related.
From my experience, music encoded in Dolby Atmos tends to trigger these failures more easily. This album is in Dolby Atmos and features very short tracks (most of the early ones are under a minute), which I suspect creates an especially unstable playback scenario for Sonos systems.
