I just observed, that lossless files (both Flac and Apple Lossless) are not transcoded in Plex Media Server 1.2.5.2966 running in a Docker image on Ubuntu 16.04.1.
Has anybody else observed the same?
The log of the relevant playback attempt.
Yep, I’m seeing the same behavior on 16.10 after upgrading. I am able to transcode FLAC to AAC (e.g., stream FLAC to my iPhone), but unable to transcode FLAC to MP3 (e.g., Plex Web in Safari).
I haven’t reviewing the logs for other playback attempts, but it works fine in Chrome and doesn’t work on my Samsung TV or when syncing to my iPhone. I assume these are all FLAC to MP3 transcodes.

The new server update fixes this. Thanks for the quick fix.
