I can get some passthrough like dd ac3, dts in mx player, but dts hd ma, and hd audio like dd true hd or atmos doesn't play any sound in kodi when passthrough is selected. Fw005 with Fresh factory reset, wiped cache, new installed kodi with only passthrough enabled, my samsung k950 atmos sound bar should work as my 4k bluray player works via the other input . I have heaps of downloaded files which are a mixture of dts, dts hd, true hd and atmos. Atmos won't play in mx player. It's got me really stumped. *update* looks like the only way I can get get any sound via passthrough in kodi is if the audio stream is ac3 5.1 and i - enable dd ac3 transcoding. nothing else works. *update 2* I downloaded some atmos files off Dolby. Work both in kodi and mx player. But when I play other files that are TrueHD don't work. DTS HD works in mx but not kodi. *update 3* after messing around a bit that it won't play the truehd version of atmos but plays the dd+ version atmos. Is that a bug?
