How To Connect An External Hard Drive To A Tv How Do I Connect An External Soundcard From My Laptop To My DJ Mixer? What Cables Go Where ?

How do i connect an external soundcard from my laptop to my DJ mixer? What cables go where ? - how to connect an external hard drive to a tv

I've recently bought to live in an external sound card (M-Audio Audiophile USB) record mixes on my DJ mixer.
The manual of this sound card is terrible, and does not explain how I connect my mixer (Pioneer DJM800)
I want to know what to go somewhere the son.

Thank you for your help!
