So I thought I'd rustle up an older thread because I, too, am having issues with cataloging (library mgmt) and playing Dolby Atmos albums that originally came in an MKV container (or that I ripped from Bluray to MKV). Another part of playing Dolby Atmos albums is that I often do not want to fire up the display (in my case a UST projector and automated 120" screen).
My first iteration was to play the MKVs via my Zidoo Z9X media streamer. Luckily the Z9X has an online and iphone-based GUI that has one app area called Media Center. It is a folder-based search and works just fine, but there's no metadata and no chapter/track info. Usually the Z9X physical remote or the iphone remote successfully moves through tracks ok, but kinda blindly.
I recently bought a Ugoos AM6b+ Android-based streamer and put CoreELEC (customized code that runs Kodi) on it in order to properly play Dolby Vision Profile 7 FEL (and all other DV flavors) into a tv-led DV display (only box I know that properly does it). So since this box now runs Kodi I decided to take some of my fave Atmos albums and convert them to MKA since
@HomerJAU informed u that the newest Kodi accepst and reads MKS basic tags. And it does. With Chapter Editor in MMH I added chapter tags and CoreELEC reads them into my music category (after adding some XML). Not a lot of metadata, but suffices.
All of this is being done with local hard drives, but Ugoos won;t tell me what the max hdd size is on their unit, so I am thinking I might just use my Synology NAS as the source. And folks told me the best way to do that is add a Plex server. So I did. And was gonna add a Plex add-on (Plex4Kodi, for example) to the Ugoos but first I noticed the generic Plex front end on my pc (where the server is) does not read MKAs, and certainly only MKVs if you put them in the Movie class/category. What a pain.
So, I think what I'll do is see if I can find my NAS via Kodi (not Plex) and run my setup that way. If I can't I'll have to find out what hdds I can hang on the Ugoos.
Edit: Do you think my Plex doesnt read MKAs because, in my case, in every one of my examples, there is an MKV file too (as I said I converted each one, but didn't delete the orginal MKV). Maybe it sees the MKV and shoves the MKA to the back?? Dunno
