X900h ps5 sound settings. I’m confused Hi sorry if this has been asked. What sound settings should I be using for my ps5 on this tv

The tv has 
eARC - enable yes or no?
Digital audio out - Auto1, Auto2, or PCM
Dolby digital plus output - DD or DD+

Ps5 has 
Linear PCM
Bitstream Dolby
Bitstream dts 

Which of these should I be using. The ps5 is connected to the tv hdmi 4(enhanced) and the tv is connected to an onkyo sr-444 amp via arc

Many thanks
