I'm wondering where to start with this...
We've recently got our three ZP100 Sonos units back out of storage after a house rebuild and one of the units is failing to play our music collection. Two of the units should be hard-wired to the network and one operates wireless. Currently the wireless unit and one of the wired units works fine but the third in the lounge just seems to skip over the tracks when trying to play a album in the desktop controller. If I try to play one song the controller shows a message "unable to play 'xxxx' the song is not encoded correctly". If I try to play this song on any of the other units it's fine...?
The failing ZP100 is located in a cabinet under our TV and next to an XBox which is similar to how it was before the house renovation project when it seemed to work fine.
The failing unit is happy streaming content via Apple Music or via the TuneIn radio service - just not from our local NAS (again hard wired into the network)
Can anyone give me some steps to help start identifying what may be going on?
