No game audio in OBS with PS + capture card (mic & chat work fine)

Hi! I’m streaming on Twitch using my PlayStation through a capture card to my PC with OBS Studio.

I’ve run into an issue where OBS isn’t picking up any game audio from the capture card.

My mic is working fine. I can hear my friends through game chat but there’s no game audio showing in OBS at all (no levels in the mixer). I am using a chat link pro for my wired headset.

I’ve already tried:

Checking audio input/output settings in OBS

Making sure the capture card is selected as an audio source

Testing different audio devices

Following multiple YouTube/Google tutorials

Nothing seems to fix it.

Has anyone run into this before or know what I might be missing? Any help would be really appreciated!
