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.
