Kodi didnt support true hd format

i have sony a80L tv and sony ht a9 sound system.
i downloaded remux movies which contains both atmos and true hd atmos. i connect sata hd with my tv and played movies using kodi 21v player. And also i enabled passthrough in tv as well as in kodi settings too. when i played atmos sound track it works correctly, but when i played true hd 7.1 its not showing true hd and sound quality also not good like atmos version. How to make it work.
