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.

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.

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.

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

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.

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.

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.
