Cannot Play Some Tracks, Error "Not Encoded Correctly"

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.

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.

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.

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.

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

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

Have you checked the tracks wherever they are on your system, to see if they conform to the supported formats?

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.
