capture card, obs, ps5, people not hearing the game

[GiacomoSports]

Alright so I have my ps5 into a capture card into the pc running OBS. I have a pair of headphones into the capture card and when i play a game I hear the game no issues. When I play back a test recording I can see people will hear me but they do not hear the game sound from the ps5.

Any idea how in OBS to change something so they can hear the game as well as me
