External Audio track/file support

[mgeale]

With 4k media taking off and Dolby Vision (currently) limited to a container than can only support 5.1 audio, I would like to see plex add external audio support like subtitltes or something along the lines so people can play “bigger” audio files on their full home theater systems…such as ATMOS or DTS-HD. I know it isnt as simple as that, but something like that would be nice.

Alternate [external] Audio Tracks

Directors Commentary, Dubs, etc.I'd love the ability to load external audio tracks for directors commentaries, things like MST3K-style alternate audios, dubs, etc. Sometimes these are in MKV, but sometimes you find them as separate files. Would love to be able to play simultaneously!
