Hyperx Cloud Alpha Headset does not work on my laptop?

I recently bought the headset Hyperx Cloud Alpha and it works great on Ps4 but when I connect it to my laptop, only the headphone works but not the microphone. I have an Asus Zenbook Pro with the audio driver Realtek HD Audio Manager where I can also set headset. Hope you can help me.

The microphone works only if you use the external USB sound card that came with it

In my delivery was no external USB sound card included
