Thanks for the information! I suspected it was to do with the customized ffmpeg/ffprobe when MovieFan.Plex informed me earlier in the thread.
As you mentioned, it is a cosmetic issue for me. It scans in and gathers metadata properly, though it’s defined as 5.1 by Plex’s Transcoder executable, which incorrectly informs the WebUI, iOS Plex Dash, and Tautulli. EasyAudioEncoder does it’s thing properly and converts to WAV (to 8 channels or less), then converts to Dolby Digital Plus (Max Quality - 1024 kbps max). My sound system app shows a 7.1 Dolby Digital Plus output.
Another issue, and I suspect it’s more to do with the way EasyAudioEncoder is built rather than how Plex implements it, is the audio processing done during those conversions (see this post onwards). There’s some large volume/limiting fluctuation artifacts that can occur during establishing Dynamic Range Compression values, though that’s an entirely different issue for another post (I’ve made one here).
