just like the title says some of the titles just don’t play audio on the Ps4, it’s not muted and the shows work fine on both mobile and PC, I feel it’s worth mentioning they have “Unknown—VORBIS Mono” listed as the audio format, they that are in .MKV format, and they don’t want to be played on the windows 8 media player.
I just tried a VORBIS Mono video file and it plays as expected with audio. If you could send us a sample or at least provide the media xml info of the file I could look into it more.
