Not sure when it was implemented, however I’ve noticed that when I go to select a different audio stream in the iOS app, it now displays the audio stream title in a grey font beneath the language and type of audio. Server Version Version 1.14.1.5488 linux. Don’t have my iPad in front of me, but assume it is the latest version of iOS app.
This does not display in plex preview for Roku or on Plex Web (although if you click get info on a movie via web, it will display all data, including audio track titles, just not in the audio selection box)
Anybody know if any other clients will be using this tag information and implementing it in the UI? Seriously would love to have this feature (finally!) to better distinguish between commentary tracks, etc. I’ve taken to labeling commentary tracks as different languages and keeping a mental note to know which is which but it would be great if this was finally implemented accross clients…clearly the data can be read, just add a new field in the UI…please? 
tl;dr iOS app can see audio stream title tags and displays them…need more clients to do so, specifically roku with all the “fixing” coming our way…
