Dolby Atmos/DTS:X

[frkonalsh2003]

Not sure if this belongs in this forum but I have an issue that I noticed recently. I tried playing The Batman on my non Dolby Atmos/DTS:X receiver last night which somehow got downgraded to Dolby Digital. I know Warner Bros for some reason defaults their movies to lossy audio and you have to manually select the lossless option but I think they finally stopped doing this. I think the Dolby Atmos track might be causing some compatibility issues with my receiver which does support lossless audio (Dolby TrueHD, DTS-HD Master Audio, and LPCM)

I tried other Dolby Atmos movies such as Batman 89, Batman Returns and it unfolds to Dolby True HD.

I played a BD (non 4K) region B copy of Jurassic Park and for some reason defaulted to the core DTS track instead of the lossless. Tried to manually change it with no luck.

I'm not sure what is going on here.
