FLAC Transcoding no longer working

[tmwsiy]

Not sure if it is a result of upgrading to 5.2beta1 or not but I can no longer play FLAC.
It just won't play on either mobile app, web, or Sonos.
I have not touched the default transcoding settings.

I have ensured that the transcoder is still installed properly and the settings are correct.

The red box from log shows where I tried to play a track.

I'm having this same issue on the 5.2.1 release. I'm running the WAR version on FreeBSD 10.1. The default transcoding entry includes m4a files, and they are playing fine.
