A:AnswerFound out only headphones can be connected via bluetooth. Ps5 doesnt support bluetooth audio systems. Other then headphones. My soundbar is bluetooth. And ps5 doesnt connect to it unless it goes through hdmi. Which would decrease the usability of the hdmi 2.1 function. So the tv is the connection. Not the system.
A:AnswerYes you can as it is backwards compatible. Just keep in mind with some games you may have to use a ps4 controller. Some you can use the ps5 pro controller.
