@maxmp thanks for answer
I use a wired headset.. 3.5 output.
1- Did not worked :(.
2- My mistake.
3- When I choose output for wired headphones says "dvc not supported" for wired headset/aux. might be something to do with the samsung variant (UHQA PCM)? On samsung settings doesn't allow to choose ATMOS because "the current source uses 32 bit".
thanks
