Reverse line-in signal?

Co

I want to have my Playstation sound on my headset and the PC sound to be able to communicate with my friends via Discord while gaming. That's why I'm now directing the Playstation sound from my screen to my laptop via an AUX cable. Since my laptop doesn't have a line-in input, I bought an external sound card https://www.amazon.de/...07HMWHBXS/

As far as everything works as I would like, I can hear my Playstation sound as well as the sound of my laptop on my headset, which is connected to my laptop. However, the Playstation sound is reversed, so left and right are swapped. However, the laptop sound is the right way around. Is there a possibility to reverse the line-in (Playstation sound) or is my sound card possibly simply defective)

Why not discord on ps4?
