VERO 4K PLUS and ATMOS ENABLED SPEAKERS

Hi, I know this question is asked many times before and I think I read all the replys but I still have the same problem. I can’t get any sound from my Atmos enabled speakers. I am using vero 4k plus with my Sony dn 1080. I am using the passthrough option enabled, Sync Playback off, Adjust Refresh Rate enabled. I see True HD on on my AVR screen but not Atmos. As I know Atmos is part of True HD but the thing is I get no sound from the Atmos enabled ones. I use 5.1.2 setup. Other things are all good. I get sound from every speaker except that two.
Is there anyway to change the subtitle font to calibre and is it possible to use the remote with Samsung tv ( the CEC thing) Thanks in advance.

Note: All the movies I tried has Atmos and also tried a file called something with helicopters Atmos demo.
