I have recently started having an issue where some tracks will not play with the error "track not encoded correctly".  I have moved my Sonos Bridge away from my wireless router to see if this helps, and although response times are a lot quicker I am still unable to play some music.  I have generated a diagnostic report - 4066834.



The issue only seems to have started when I installed a new router, so it is very possible that this is causing interference due to the signal being better.  My bridge is hard-wired to the router so I have probably moved it as far as I am able.



Many thanks in advance for any help you can provide.
I've recently started getting the same issue with a number albums.



The files worked fine until I started using an Amazon Echo Dot in my office. My music library is largely iTunes based and stored on a local NAS.
Well, not sure I was any, but you're welcome in any case. I'm watching this thread to see what the Sonos reps have, I'm always up to learning something new.
Thanks for you help
Understood. Note that the Sonos player (built in to the speaker, not into the app) is not the same as iTunes. In fact, that's why many of us are hoping that Apple follows Spotify's lead in integrating the "cast to Sonos" feature that Sonos has published.



Since you seem to be able to cause it to occur on the same tracks repeatedly, I will have to defer to Sonos to take a look at your diagnostic, and see what information they can glean from your log files.



I hope you're able to resolve this issue quickly!
The format is AAC 44100 Hz, the entire album (Les Miserables) was encoded by iTunes at the same time using the same parameters, the files are stored on a NAS, and most of the tracks in the album plays fine, but a few give me that error. Currently I am listening to them in iTunes and they all play fine.
Have you checked the tracks wherever they are on your system, to see if they conform to the supported formats?
I also having this problem, has been for a long time now, I will play an album and some songs are skipped with the error "Enable to play the sond is not encoded properly" these are songs that used to play ok and play fine in other players

My confirmation number is: 7356866.
I saw this suggestion from a technician (to connect directly to the NAS, without connecting to the router first) in another post. How do I find the path to the NAS now? There is no valid option in the setup for the library



It would be a good idea to continue troubleshooting on the phone. Please call us up and reference case number: 170313-002045. You can find our contact information here.

I have now connected the Sonos directly to my NAS WDMycloud via ethernet cable. Sonos is setup to hookup to my router but when I disconnect the cable Sonos disappears. My diagnostic ref is now 7186185
thank you, that does not help. I am trying to play carbon based lifeforms FLAC. No I did not encode it myself, I bought it like this. I have stated in my previous post that I have read all your suggestions and none works. I thought Sonos was a good alternative to Soundtouch but now I am starting to doubt. I do not want to play Spotify anymore, I want to play my music.
Hi, the diagnostic ref number is 7185960



The diagnostic report shows that your Sonos speaker can't decode the music files. Did you rip the files yourself? Please check this guide to see the bitrates for music that Sonos can play.

After a file fails to play, submit a diagnostic and post the reference number here. A sonos tech will evaluate the diagnostic and get back to you.
Hi, I bought my Sonos 5 on Thursday and I have battled since to play music from my library. Most of my files are mp3, a good percentage are wav and some are flac and alac. none of them plays. I am a bit disappointed. I bought a Bose soundtouch 30 and sold it after a week to buy Sonos but now I am back to square 1. I have read most of your suggestions but none of them works, "cannot play file, …not encoded correctly is all I get.
Mine is doing it for Apple Music only... Skipping songs partially played and giving me the encoding message. Diagnostic 6254717.



Hi Briman.



There's quite a bit of wireless interference showing up which is causing communication errors leading to the errors you've described. Please start by changing the Sonos wireless channel, here's how.



It may also help to look around your Sonos units for any third party device which could be creating a wireless signal. If you find any such device, try moving it away from your Sonos units to see if that helps.

Same problem her. My diag number is 5612282

Any advice?




Hi MrHau,



We're investigating this issue and have created a support ticket for you: 160331-001726. Please give us a call and reference that number. You can find our phone number here.

I couldn't find a direct link to be able to stream other than with MIXLR which sonos doens"t have an app for. You could try contacting the station to ask if they have any direct streams.
I am trying to add this website to My Radio Stations - http://mixlr.com/weather-for-the-blind

I can successfully add the station. However, when I play the station I get the error message that Sonos is unable to play the track because it's not encoded properly. The station is also available here - http://weatherfortheblind.org/

Is this a station that can't be played or am I doing something wrong? Thanks! Eric
keeps stopping them half way through and moving through the queue. I've submitted a diagnostic as 4891029

Hi Seann, like Chris said and after reviewing the diagnostic your system is experiencing a high level of wireless interference. I found errors when playing audio stored on the iPhone to the Sonos. Can you try to change the wireless channel on the router to 1, 6 or 11 and make sure it's on fixed and not wireless auto change. Once you have changed the router's wifi channel test the system for about 15mins and submit a diagnostic for each.



Let us know how it went when your PLAY:5 is wired to the router like Chris asked.
It doesn't have to be a bridge. All Sonos units are bridges. When you hook one Sonos unit to your router it then creates Sonosnet (dedicated wifi for the Sonos system).



You could always try hooking one of your units to the router temporarily to try Sonosnet and see if it resolves the issue.
thanks chris,



I'm using wifi only, is sonosnet when you get the bridge?
Diagnostic sound like best idea ...sounds like interference. Are you using Sonosnet of wifi only method (Sonosnet always preferred to avoid dropouts on wifi).
