Neumi Atom 4K as an Atmos music server

[nikomen]

Correct, the Atom 4K plays MKV files that contain Atmos audio. The Atom 4K connects by HDMI to my Denon AVR which then plays that Atmos audio over all 7.1.4 channels. You must use HDMI between the Atom and the AVR.

The Atmos 4K does seem to accept USB 3.0 drives. I am using a portable SSD drive over USB 3.0 and it works fine.

Like you, I use a separate method for playing non-Atmos multichannel audio (5.1 MP4, FLAC). I put those files on a USB stick connected to my Sony X800 Blu-Ray player, which is then connected to my Denon AVR.

If, at some point in future, the Atom 4K supports MP4 and FLAC 5.1 audio, I can use the Atom for all of them. However, I contacted Neumi about this and they said that to enable support for those other formats would require a "new chip". Therefore, it is unlikely the current release of the Atom 4K will be upgradeable (i.e. firmware update) to support that.

I'm assuming it's just going to play back the MKV files as one long song. Some people here create .cue files with MMHelper
to let them play back the file as songs. Have you tried that?

Three MKV Atmos albums I have play like regular albums, where you can forward or reverse to different tracks. These have properly embedded cue points. However, one of the MKV Atmos files I have ("Suite Cubana, Vol. 1" from NativeDSD) plays only as one continuous file. Thanks for the tip about MMHelper, however, I'm on a Mac and it seems MMH is only available for Windows.

Out of interest, does this dsd file have a .dsf of .dff file extension. And has the .cue navigation file been amended to suite the file extension?

The download from NativeDSD is in MKV format, not DSD.
