muveedkhan where is that build so i can test it? Best Regards

That build is here:-

Rockchip – LibreELEC

but you have nightly builds here: test.libreelec.tv

libreelec-rk3328.arm-9.1.501-rock64.img.gz

Tested android-7.1.2-rock-64-rock64_atv, surprisingly what we are expecting in Libreelec (Dolby Atoms, DTS-HD MA, HDR & etc.) all are working

only one limitation is App's, you can not install all apps on this Android version (compatibility issue, any way other thing are working as expected)

Enjoy your ONKYO, Denon, Yamaha high end home theaters with HDR + Dolby Atoms

@ Kwiboo : please can you give some updates, or have you stopped working on ROCK64 ?

Is that true HD audio passthrough is purposefully disabled in libreelec (kodi) (DTS-HD, TURE-HD & DOLBY ATMOS)O?

If it is not true, why it is working in Android 7.x.x but not in other version

if yes, the when it will be enable (you mentioned it is under development it will be enable in Linux kernel 5.x)
