No audio with AC3 5.1 on Premiere+

SpunkymankerSpunkymanker Posts: 5 Plex Pass

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 (

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.

    Spunky, a lot of us are having this exact issue. Roku released 7.6 on 4/11 so download it and give it a try! I haven't been home yet to check it out, but do report back!

    i have confirmed this is an issue with the udpate, if you rollback to it resolves the issue. :)

    I've been struggling with the same issue. Only Roku plex client have no audio but other cients (i.e. Web, iOS etc.) all works fine. Zac, any idea how I could get an older version of PMS and rollback? Thanks in advance.

    Can you guys confirm that the files with no audio are, in fact, AC3...and not EAC3? As noted in my other thread, my Ultra wasn't abiding by my universal Roku setting to support only AC3/DTS. It was still trying to stream EAC3, which caused no audio.

    Same Problem here, No sound with 5.1 AC3

    Updating to Roku 7.6 seems to have fixed my Plex AC3 issues--now I just have the random split second sound delays.

    Indeed, the update to 7.6 has fixed the issue.

    I've noticed the same issue with random sound delays (just drops out momentarily), and on a few occasions I've lost sound entirely. Only a restart of the Roku returns sound.

    I have Roku 7.6 and still all AC3 have no sound. 5.1 or stereo.

    I found I had to go into the Roku audio settings and set everything to stereo. It now works.
