Ps5 Audio
They are bound to have Atmos and DTS-X support for movies due to the 4k Blu-ray player PS5 has, it would be incredibly stupid to not support the audio formats that 4k movies use.

As for games they are starting with headphones for their 3D tech as it's the simplest to do it on, they then will go to Tv's then surround sound systems last.
I would guess that games would just playback as they do now for TV's and Surround systems until Sony update them for the 3D stuff.
