Play PS4 sound on PC?

(I hardly know my technique, but I have the following theory)

If I connect the PS4 sound with a jack cable to the PC to hear the PS4 sound with the headset connected to the PC, will the sound be improved / louder?

Because in my PC is indeed a sound card installed over the sound of the PS4 goes and then in my headset…

If the sound does not get better / louder, does it stay at least as good?

The sound may get louder but we can get worse
