5.1 Audio via PLEX app on ROKU all Devices

Plex Players Streaming Devices

Server Version#: 1.20.3.3483
Player Version#:6.6 Build 12
All ROKU devices running os 9.4.0
All devices are not playing the 5.1 audio properly (No Voices Center Channel seems to be missing.) from the new ROKU os 9.4.0 using the PLEX app v6.6 Build 12.
I was able to force ROKU to reinstall software 9.3.0 and it plays HEVC 5.1 Audio from within the MKV package again . I don’t know how long this can be done ROKU will only allow this for so long, but the ROKU app for PLEX needs a fix for the ROKU OS v9.4.0

Responded to another thread, but I’ll include the same response here too for posterity :slight_smile:

It seems there may be a Roku firmware regression in 9.4, not down mixing 5.1 AAC to 2ch AAC. We’ll file a report with Roku, but in the mean time we’ll need handle this by converting the 5.1 AAC to 2ch AAC when applicable. We already do this when we detect surround sound and convert to 5.1 AC3, however, we’ll need to do this when we have to output 2ch instead of relying on the Roku to down mix it.

It looks like that’s been included in today’s Roku Preview Channel update, right? If so, that was fast.
