Anyone out there will similar issues? Or can assist in any way?

Your logs show your server transcoding the audio from aac to eac3. Check your Roku’s audio settings. It’s telling Plex to make the conversion but if you don’t have a way to play the eac3, then playback will fail like you are seeing.

@MovieFan I appreciate the reply, but I looked at the settings for both the Roku and the plex app for Roku, but couldn’t find a way to adjust it that way.

It should be the actual Roku setting for audio. Look for something that says Dolby.

Did you try DTS? Sorry if i want clear, but Dolby=eac3. The eac3 is what appears to be the issue.

As far as I can tell, the specific issue is that when the audio codec isn’t supported by my Roku, it tries to transcode and the transcode fails. AAC Stereo works, but AAC 5.1, TrueHD, and even FLAC Stereo all fail while DTS-HD MA work…

I am having the exact same issue with my Roku Ultra box. mp4 files won’t work at all and mkv files with h265 codec simply will not work. mkv files with h264 does.
