PMS fails to serve up almost all 16bit 44.1kHz flac files to SONOS and reports “Unable to play - the connection to Plex was lost.” This error is reported in both Android and Windows SONOS controllers.

PMS will play any mp3 file via either the Android and Windows desktop SONOS controllers (S2). Unfortunately, both the NAS software (including Disk Station Manager, v: 6.2.4-25556) and PMS (v1.) were updated during this time, so I’m not sure where the issue started, but this is what I’ve been able to establish: It has been working flawlessly until the last couple of days.

I’ve been using PLEX Media Server (PMS) running on a Synology Diskstation to serve up local music files to the household SONOS system.
