Newer Dolby audio (7.1, Atmos) not playing properly

[mooch91]

Hi all,

Having trouble with 7.1 audio (True HD + Dolby Atmos) on my rips, and I'm not sure what in the chain of my setup is failing...

My setup is: MakeMKV > True NAS > Jellyfin > Roku (Jellyfin app) > Yamaha receiver.

I've tried on both a Blu-Ray and an UHD disc. The True HD + Dolby Atmos stream is being decoded from a PCM 2.0 signal on my receiver and doesn't output to all channels, including my subwoofer. The 5.1 streams seem to be recognized and work just fine.

I always select all of the English audio tracks, and I unselect those in other languages when ripping. Jellyfin lets me select among all of the audio tracks.

I have confirmed it's not the receiver. It can play the audio and it works as expected in all channels when I play the disc to it directly on a Blu-Ray player.

It's either in the rip, Jellyfin, or the Roku.

I'm not super familiar with audio codecs, but this is what the web tells me the Roku Ultra should play:

• Digital stereo over HDMI®
  
• DTS Digital Surround™ pass through over HDMI
  
• Dolby Atmos® decode via HDMI*(*Requires Dolby Atmos compatible speakers.)
  

Two of the rips which don't play audio as expected are as follows:

• Dolby Atmos (on the disc); Dolby True HD + Dolby Atmos (in Jellyfin)
  

Rips which do play audio expected seem to be:

• DTS-HD Master Audio 5.1
  

Can anyone help?  Transcoding issue? Can provide more info as needed.

Thanks!
