Reproducible Playback Failure on Sonos Arc+Sub+Era300 with Apple Music Dolby Atmos Album

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.

https://music.apple.com/jp/album/tchaikovsky-the-sleeping-beauty-childrens-album-piano/1825381287
(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.

My speculation is this:

Any song played thru Sonos is buffered. Short tracks leave little time for the buffering process between them hence the drop issues. Especially tracks with little to no dead space in between. Think drinking water in sips versus from a fire hose. Atmos tracks contain much more information versus a stereo track. However as I said in the beginning… this is just my speculation 🤔

I agree with you idea. But if so, w​​​​hy can’t Sonos support reproduce our situation? That’s why I guess there might be another factor(or, Sonos support is just lazy).

And the same Album on Amazon Music works perfectly even with Atmos format. The hardware buffer should be enough for Atmos, and I think this problem can be solved by software update.

Assuming that all Sonos devices have enough spare memory not in use, I’d agree.

    Evidently Apple Music uses a DD+JOC streaming codec vs Amazon Music AC-4 IMS streaming codec. The latter requiring less data processing to achieve the same immersive effect.

    Now don’t ask me what all the above jargon means. Below is a link to a page that is partial AI Generated and human interaction with a Youtube video.

    Take it for what it's worth or not. However, it does IMO shed some light as to why Apple Music Dolby Atmos streams require more processing vs Amazon Music thus resulting in drops/skips for the former.

    Here’s another link from 2021 that speaks to the differences between Apple Music Dolby Atmos streams vs Amazon Music/Tidal Dolby Atmos Streams

    The conclusion IMO is that Sonos probably has little to no way to rectify the Apple Music Dolby Atmos issues; unless they can somehow introduce/free-up more available processing memory. Admittedly, IMO Apple Music Dolby Atmos streaming on Sonos isn’t a total failure as the issue seems to be most noticeable with short 60 seconds or less tracks.

    Thank you for your explanation in detail.

    I hope Sonos support members check this thread and solve this problem as soon as possible.

    I updated my Sonos system to 93.1-74010 and initialized all of the components.

    It looks like the problem is resolved.

    I’m not sure whether the update or the initialization solved the it since I did both at the same time.

    But it’s worth a try.

      What do you mean by “initialization” ?

      I meant removing my system from App and doing this

      factory reset to all Sonos products.

      The factory reset is usually a bad idea and best avoided outside the specific situations Sonos recommends it for or after cntacting support. It rarely solves other issues, just makes extra work and deletes important diagnostic data support can access.

        Changes were made to Apple Music playback in the latest player firmware, although the published change made also appears to have fixed some other issues users were having with Apple Music. The factory reset of all products was likely unnecessary.
