Dolby truehd atmos

Recommended Posts

Hey group. New to forum, but have been lurking for awhile. Running hdmi to everything and also running the fire cube 3rd gen. I have kodi running on both. Set things up on kodi and have the box sending audio through hdmi to my amp (same as the cube). The 4900 will play the dd+ Atmos fine. Truehd however is not passing through (settings are set correct on kodi). My amp reads 2 channel pcm. Is there a setting somewhere to enable pass through?  In the audio settings I have set it to manual and turned on all formats. Trying to compare apples to apples to see if I even need the cube.

No settings on the buzz It should be enabled through your amp The buzz does allow passthrough 

Hmmm. So you are getting truehd pass through?  Are you using kodi?  I’m asking because this is such a stump for me. Tonight I’m going to try to switch spots with the cube. Maybe it is a handshake issue or hdmi issue.

Well. Switched out cube for buzz. Tried buzz with settings set for both Plex and kodi. Nothing but pcm 2.0 with all my truehd files. Dts and dd+ Atmos both work and switch over on amp, but notta for truehd. Keep all the cables the way they are and switch back to cube and all works. Nearest I can see is it is not letting truehd pass through.

Thanks! I will. Also not working in Plex. That’s why I leading the way I am. Curious, do some have a setup they can share where they are getting truehd with buzz?  As mentioned Atmos with DD+ and dts hd is all good.

If there was they would post it

Ok. Thanks. Just hoping that it gets some attention being an older box and all. I know most discussion centers around iptv, but it does have the juice to run within a home media network. I will be patient and hope 🙂

So it has been a little and still no update on a fix for Dolby Atmos truehd. Can any light be shared at all? I’m looking at picking up a couple more boxes and I was hoping to go with buzz. Hard to so without an explanation or solution. I enjoy Dolby truehd using Jodi to stream high hd movies with the box. Shield and Amazon fire cube have no issue. Hope some one higher up can chime in.

Pretty sure right now, they are super busy with the launch of the Android 13 devices, with BuzzTV 6. 

Not a common setup for many people, so hard to even get too many people to test, on different boxes.  And Android 9 boxes (as in your 4900) I am sure handle it differently than Android 11 boxes (like the X5, Classic, etc..).  Not sure how Android 13 buzz boxes will handle it also, since they are not in public circulation yet.   On my classic, since I don't use any surround sound system and it tries to do passthrough, I need to force it to "never use surround sound" (option on Android 11 boxes), otherwise I have some 5.1 encoded streams that hang.

Thanks for that insight. Yea. I’m particular and wanted something different than a shield. I’m kinda an audio snob. I’m wondering if the other newer boxes are actually passing through truehd as advertised or kinda doing the same thing.

They are not in circulation yet, so kind of hard to say at this point.

I apologize for the late response on this

We looked into it 

 

atmos passthrough works fine.. truehd cant be passed through hdmi, bluray players decode it directly basically 

 

for atmos passthrough to work it needs to use EAC3 container. Which is what Disney+ uses for example.

To add to this

Truehd cant be passthrough, its a bluray format, its decoded on players, some receivers can decode it but it cant be passed through, its a lossless format takes a lot on bandwidth

Thank you for the response.  The fire cube and shield both pass through truehd. Just for knowledge. I do appreciate the response. 

Pretty sure they hardware decode it as they both have Dolby Licences
So there is a difference between Hardware Decode and Passthrough.

True but through bitstream or passthrough truehd will still be truehd and my amp pics it up as such. Like I mentioned earlier, I’m using the 4900 different than most. But, good for education purposes. With the fire cube and a truehd source. I was just hoping to ditch some devices.
