Thanks a lot DCLong57.Pretty much every PS game is only 5.1 DD, very few are DTS 5.1 but where it does matter is if you're playing bluray discs. Movies are now DD Atmos... DTS-X but there are virtually no games on PS in Atmos. The X-Box One, X and S have games in Atmos. If you're more concerned about movie soundtracks, the PS5 from what I've heard does not output Atmos or DTS-X via eArc so if your BluRays are your main concern and not Atmos or DTS-X, select DTS. Both should play from BluRay.
