So I've been trying to fix this issue with routhing my PS4 audio through the headset plugged into my PC for a few days and was hoping maybe any of you guys can see an issue here I've missed. So almost all guides on routing ps4 audio to your PC state that the easiest way to do it is via these steps: plug aux cord into PS4 controller and line in port on back of PC > change all PS4 audio to output through headphones > go into line in device in windows sound settings and tick the listen to this device option.
Issue I'm having with these steps is that when I plug the aux cord into my PC the line in device doesn't show as plugged in. I've tried using every other port, checked that the device isn't disabled or hidden, swapped the aux cord for a brand new one. Basically i'm lost and out of ideas as to why this won't work.
I've attached a few a screenshots of the sound properties on my PC when the controller is plugged in. Let me know what any of you think
