Hi -

Currently, the Apple TV has limited support for Atmos content, and Infuse (6.3 and later) will support Atmos when using E-AC3 audio tracks, and a few sample files can be downloaded at https://www.dolby.com/us/en/guide/dolby ... ilers.html Unfortunately, Atmos with TrueHD audio tracks are not currently supported.

More info on the audio options available in Infuse can be found here.

Also, we're working to encourage Apple to add more versatile options for Atmos and other audio codecs. If you have a moment to send them a quick message, you can let them know this feature is important to you as well.

More info on how to send feedback/suggestions to Apple (along with sample text you can include in your message) can be found here.

Wanted to share the setup and my results:

MakeMKV = 1.15
MKVToolNix GUI v44.0.4 (Domino)(64bit)
LGWH16NS40 = FW 1.02 (thanks for the FORUMS help on this)
Infuse 6 Pro (latest) (which has support of Atmos https://support.firecore.com/hc/en-us/a ... ions-tvOS-)
Apple TV 4k (TVOS 13.4) Audio settings are Set to = AUDIO/BEST Available. Which means Audio will be sent as uncompressed, multi-channel LPCM (up to 7.1 channels and 24-bit)


UHD4k = 85GB mkv (which included all audio options, subtitles, all of it.)

Opening the MKV in MKVToolNix —
I can see:
TrueHD Atmos codec, properties say 8 channels, 24bits ber sample and is the Default Track

along with the other audio tracks:
AC-3
DTS-HD Master Audio
DTS
AC-3 (English 5.1)
AC-3 (French 5.1)
AC-3 (Spanish 5.1)
Playing off Wired gigabit network, SMB to Apple TV 4k with Infuse 6Pro = playes fine, but audio on Onkyo RZ630 displays TRUEHD 7.1, and not Atmos.

It would seam the audio is there per the mkv details viewed using MKVToolNix. Not sure if Infuse 6 Pro's Atmos implementation needs the file in a different format?

Just wanted to share a summary of what I did in case it was helpful.

• Using the SMB Protocol which support the great Library and Artwork, playlists, etc that makes Infuse a great option, would only get 240-270 Mb (Megabit, NOT MB megabyte)

• I have a Cat6e Gigabit wired connection and I noticed on a 4k MKV, the movie paused twice during normal play.

• That same file now get 950 Mb (Megabit) and 4k not only played without issue, it allows for very usable scrubbing of the playhead back and forth, previews pop up fast.

• I then removed the SMB share from Infuse and am just using the FTP mapped drive.

Very useful!

I've been useing NFS and had an even slower connection, around 200 Mbps. That was fine for regular playback, even with 4k streams over a wired LAN, but any seeking never worked properly. I'm a professional IT guy but sometimes you don't see the forest for the trees and I never thought to monkey with other protocols. I can't even tell you why I went with NFS, I probably had other shares set up and just left it at that.

Just switched to FTP and am getting the same 900+ Mbps, seeking and chapter skip are working great!

I'm hoping, too, that Apple decides to support ATMOS in a TRUEHD container, which is really the root of the problem. There's no free/easy way to convert a TRUEHD track to EAC3, but there are expensive/difficult ways!
