PS5 doesn't play Dolby TrueHD 7.1

[Edenbeast]

Hi,

I was visiting my brother, because he just purchased PS5 and we put Godzilla KoM 4k to check how it will be like on PS5, btw his Sony home theater doesn't support Dolby Atmos, so naturally it will play Dolby TrueHD via bitstream, but instead it played the Dolby Digital 5.1 track, and when changed the audio output to play the TrueHD track the two rear speakers went mute!!

P.S: We tried the 1080p BD and it plays the Dolby TrueHD 7.1 perfectly!
