I've tried Kodi v17, Plex, and SPMC with a variety of settings and I can't seem to get DTSHD to passthrough to my Denon AVR. The only time it ever works is with a clean install and Kodi on the first run, but if I leave and restart the app, it won't work and I get silence. If this is working for anyone, can someone share their settings?
DTS HD contains a DTS track, so at least that should work. DTS HD will most likely not until the update to N (in theory IEC passthrough should work for the HD-Formats and Nougat brings that to the table )
