Unable to play song ‘song’ - the song is not encoded correctly. Issue since 15.2

Since the 15.2 release there is quite a few songs that display this error when trying to play them.  These seem to be mainly songs that are not lossless.  They were purchased over time from Apple Music.  They will still play if I use the Apple Music app, but they will no longer play from Sonos app.  I suspect some lossy codex broke with latest release. Occurs with all my Sonos products.

Is this a known issue?

Hi @The Etron 

Thank you for reporting the issue with TuneIn Podcasts - we were able to replicate the problem and are now investigating.

 

For everyone else, please note that there are multiple reasons for the “not encoded correctly” error occurring:

  • Apple Music used to (years ago) provide music tracks with Digital Rights Management (DRM), which results in Sonos being unable to play them. Re-downloading those specific tracks would be the only way to fix this. Other sources may have done the same.
  • Failed WiFi transmissions can also cause this error. Our support team can identify if/where this is happening and assist.
  • Actual errors in the files themselves can also cause this error - if this is the case, the same files will produce the error each time, and probably at the same point. Again, replacing the files will be the only way to resolve. Most likely to be seen with Music Library rather than with music services.

I recommend each of you get in touch with our technical support team who have tools at their disposal that will allow them to give you advice specific to your Sonos system and what it reports.

I hope this helps.

Edit: I should add that if there were an issue with our software rather than encoding/transmission issues, we would also need to you get in touch to have the issue documented and investigated.

The fact that Wi-Fi interference keeps being mentioned by support after this long of a thread of people seeing the same issue is frustrating. For me, this happens on the exact same songs, every single time. Others work perfectly fine. It’s 100% reproducible in my case.

My reply immediately before yours was in reference to @alfonsoluis’ report of seeing the encoding error with Amazon Music, therefore the most likely (but, technically, not only) explanation in that particular case is interference. In your case (looking at your even earlier posts), the most likely explanation is Digital Rights Management encrypting the contents of your older music files (for which, Sonos does not have the decryption key).

This thread relates to Apple Music/iTunes downloads in spirit, but technically it’s title shows it to be about the error message itself, so whether Amazon Music and TuneIn Podcasts are off-topic or not isn’t easy to say, but it is making the thread a little confusing, to be sure. So, please don’t be frustrated - I am not gaslighting you, I am just giving the best-chance-of-being-correct advice to particular people based on what they report. For you, the error would indeed be 100% reproduceable, and nothing to do with interference.

I hope this helps.

As a professional studio in Nashville I purchased an Arc, Sub and 2 ERA 300s for an Atmos playback system in a client room. The Sonos App will not play 25% of the library ‘encode error’ . Tried on several devices but the exact same songs won’t play. Since the ARC doesn’t do bluetooth the system was frustrating and many complaints. Fortunately I was in 14 day return period so back to Best Buy. Returned 3k worth of gear. The same issue happens on my Move with the Sonos app same songs but I can bluetooth in fine. Until Sonos can fix this there are lots of Nashville studios opting for other manufacturers like Bose etc. I love the sound of the ERA 300s but no, a single 300 does not deliver an immersive experience. Apple AirPod Max phones better immersively. If Sonos fixes this I may reconsider but will probably bought another system since they can’t seem to do so.

I appreciate this post! Has anyone found a easy process to identify and convert songs that are DRM in bulk?

There is a definite issue on #spotify and sonos. Songs skipping.. going silent. Songs not encoded properly. I have been following this topic on various threads. Seems like the problems from other streaming service is less than Spotify.

#youtubemusic has terrible functionality integration with sonos app. Spotify has best integration functionality.

So leaving Spotify for #ytmusic comes at a cost of functionality.

None are taking accountability. Trying to deflect on the user's network. It's not the local WiFi network.

Taking my Play:3 out of retirement resolved the issue of Apple Music and playlists getting error messages and not playing. I now start everything I play from Apple Music on my Play:3 (hardwired to my router) then group in other speakers. 
 

This should be a priority for Sonos to resolve on newer speakers.

This is a simple problem to diagnose, same as the rest of the thread. Older speakers without Airplay work fine, and AirPlay enabled speakers can be “tricked” into playing songs it wouldn’t before once it’s paired with the other. Can’t believe this is still an issue.

was gonna buy 2 x new move - but this problem is driving me mad - seems if its an existing sonos playlist (large one) and even when started from non airplay sonos - skips ‘encode’ incorrectly’ tracks - so re do yr entire playlists then? ffs - this is really not good

I have upgraded just about all my speakers, but until SONOS resolves this issue, I am holding onto at least one or two previous generation speakers and starting all Apple playlists and AppleMatch music on the older speakers and grouping in the newer ones to it. It’s a little annoying, but it’s been working fine for me. I just keep the older speaker tucked away and muted.

This is exactly right and how I have been avoiding the issue for months, well since the sonos app update broke everything. I can reproduce this error on newer speakers day after day with umpteen songs that now get skipped. It’s not interference, DRM, wifi issues or anything else other than the clunky, ill coded S2 app that’s at fault. Without streaming music providers Sonos have almost nobody to sell their speakers to, so I am truly appalled that they seek to blame all streaming services, without which their products have no purpose!
