How do I use Discord and Ps4?

I want to play my games on the Ps4 and talk to my friends on the laptop on Discord at the same time using the same headset. How do I do it or how do you do it?

That will not do.

Headphones into the laptop and the aux cables from the controller into the laptop. Then specify aux as playback.

But…

Just like OutOfsupport says

What do you mean. So I plug the headset into my laptop but what an aux cable from the controller

You need an aux cable.
