This app never actually play DTS audio directly. The DTS audio had always have to be converted in other to get sound. With the latest update, the app fails to do just that. That's why we're having problem. Whether there's a bug in the app that needs to be corrected or they don't wanna bother having the app go through the process anymore. Plex Media Server setting is set to convert DTS audio. It's just that the app is NOT sending the request. We're getting less and less.
At some point, I'll go back to the regular way of accessing my server. I'll say goodbye to fancy look. I want something that works without too much sacrifices. The people at the very top of Plex making the decision are cutting things down, giving us less. They think we are all using tablets, and phones. Even if that was true, they should still be doing decoding since Plex won't have its own player that would support popular formats.
