    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?

    I'm assuming you are connected HDMI from the U9 to the samsung k950 atmos sound bar? Are there any setting in the soundbar that need to be done?

    Yes direct connection, it's only the truehd variant of atmos that does not work. Dolby digital plus atmos variant works fine. Not sure if Android or kodi or sounds bar bug. TrueHD normal works just not (truehd atmos)

    I'm thinking Android 6 and KODI has no support for ATMOS. I'll have to try on my Onkyo ATMOS supported receiver. It's like HDR. Not much support yet.

    Others say when passing through an avr / reciever that they can get truehd atmos. Also other users the nvidia shield are experiencing the same issues I'm having on my minix, just the truehd variant of atmos on the k950 that seems to be the common issue. I have let samsung know the problem. As the passthrough isn't working via spmc or kodi for the k950 properly either. But mx player is playing everything fine except the truehd atmos.

    This is an issue specific to your soundbar (Samsung K950). Dolby TrueHD/ATMOS passthrough to this soundbar was an issue on the nVIDIA Shield also. User reports indicate that the passthrough now works on the Shield. I had tried to figure out this issue with a Shield user, but couldn't find any obvious cause for this issue. It may just have to do with the way the IEC MAT frame is packed.

    Yeah I thought so, God damn it, I spent a fortune on this soundbar.
    Thank you for confirming what I sort of pieced together. I hope they can fix it soon.
