Connecting PS4 vr to my amp help

loco bro

Hi  guys not sure if this is the right place to post this  so gong to post this in under another topic  sorry in advance

So basically I have a ps4 pro and I just bought the Ps4 Vr headset   My set up without  vr currently goes like this   I have a demon amp    I'm runing one hdmi cable from the back on my PS4 to the game input on the back of my amp   And a second hdmi cable from the back of my tv hdmi 1 (arc to the back of the output  1 arc on The back of the amp  and sound runs though the amp when I want surround sound  


How would I connect my PS4  to get sourround sound with the Vr ?  Does anyone kmow
