After downloading the latest version of Plex for Apple TV, my movies no longer automatically play the Dolby Digital track. I have to manually select them in order to get them to play. This wasn't a problem in the prior version for the same files that I played last night. I have the most recent versions of both the server and play, and have not changed any settings or anything else with my setup since last night aside from downloading the new app.
Any assistance would be greatly appreciated.
NOTE: All my videos are MP4s with both AAC and AC-3 audio tracks and have worked just fine until this morning.
