I have previously posted about my problems with the Language settings in PLEX here: https://forums.plex.tv/t/account-audio-subtitle-settings-how-to-get-plex-to-choose-original-audio/541808 I will attempt to outline the problem succinctly now…
There is no known setting combination in PLEX that will specify the playback of either the default, or the first audio track in a video file. Instead, it seems that when a film’s first audio track has fewer channels than subsequent audio tracks, PLEX will choose a subsequent audio track instead, even if the first audio track has been flagged as default.
This can result in the following unwanted behaviours…
• PLEX sometimes plays a commentary track instead of the audio soundtrack.
• PLEX sometimes plays audio in an unwanted language.
• PLEX sometimes plays an unwanted sound mix.
For instance, if a film’s audio track is in mono, but it includes other multi-channel audio tracks such as commentary in stereo, PLEX will play the commentary track by default, even if the audio track is the first one in the file, and flagged as default. There appears to be no way to override this behaviour. For people who watch a lot of old movies, this can happen very often. And for the less technically savvy watcher, this can be more than just an annoyance.
I have tried innumerable combinations of settings and workaround, and I have also read other people’s requests for similar features, including requests for specifying defaults for 2.0, oe 5.1, or 7.1, etc. I believe the simplest solution to a multitude of related problems that users have reported would be to add a single option to the Languages menu:
Play default or first audio track regardless of language settings.
Alternately, under the “Prefer audio tracks in” drop-down menu, an option could be added called “Default.”
In either case, the setting could play the audio track flagged as default, and if none were found, it would play the first audio track.
What do you think?
Prefer default language flags in media files if present
