I have an Edifier DA5000 Pro 5.1ch speaker. I would like to connect that speaker to my laptop. But the speaker has 3 cables, whereas my laptop only has 1 port for audio output.
This is what the back of the woofer looks like

So can someone suggest me something?
 
But you didn't answer my query :/
Nevertheless, the guy above you said something about soundcards. What are they called? I've used soundcards on my pc before. Never heard about a soundcard for a laptop
