Dolby Atmos with MD-DM16x16 and 4kz cards


 

I have a DM-MD16x16 with a DMC-4KZ-HD input card and DMC-4KZ-HDO Output card and for the life of me I cannot get Dolby Atmos going.
?
I have a Hisense HS512 soundbar and also tried with a Pioneer VSX-834 AVR and I cannot get Atmos to work, I can get TrueHD to work with the EDID tool in Toolbox but can't find an option for Atmos. EDID tool has DD+ and TrueHD.
?
I have a PS5 and Apple TV, PS5 has an option to choose Atmos but doesn't say atmos on the soundbar or receiver. I noticed when I used a 4K blu ray and set the audio to bitstream, I was able to get Dolby Atmos on the soundbar and the audio is set to HBR Compressed in Crestron Toolbox and on the switcher.
?
With the Apple TV connected, I get 4K HDR but no Atmos, most I can get is Dolby Digital 5.1, on the switcher the audio is set to LBR Compressed.
?
Any ideas or am i out of luck without buying more parts?
