No audio with AC3 5.1 on Premiere+
Using plex 4.4.1 on a new Roku Premiere+.
Connected to a Pioneer VSX-43 reciever via HDMI.
Plex media server is up to date (184.108.40.20696)
All stereo streams work fine, but any videos with AC3 5.1 have no audio. If I manually set the roku to stereo only, it plays audio, but this just isn't acceptable.
I swapped out for a Roku 3 with the same verison of Plex, and everything plays fine on 'Auto' for audio, and it sounds great.
Plex for Ps4 works fine as well.
