AAC 5.1 being down converted to PCM 2.0 by Roku Ultra

roku

#1

I have a Plex server on my Synology NAS and when I try to play back movies the AAC 5.1 audio (from Handbrake) is being down converted to stereo. Netflix plays Dolby Digital just fine so I know the audio set up is fine.

I thought the Ultra was supposed to transcode AAC 5.1 to AC3 5.1. I believe all my settings are correct on the Roku (which is attached to Yamaha AVR by HDMI).

Also, if I encode the movies as AC3 they AVR plays the Dolby Digital 5.1 just fine. Do I need to redo all my movies or is there hope?

Is this the 2016 Ultra (with the Optical output) or the newer 2017 Ultra (with no optical)? From my understanding, only the 2016 Ultra has the capability to transcode to AC3.

He got impatient with waiting on slow vanilla plex forums and clicked submit 3 times.

I have the newer model.

Thanks again JamminR! More incompetence than impatience on my part for the multi post though :slight_smile:
