PS2 and computer

[Joeyyungrocks]

I just got a ps2 and it has the 3 RCA input cord with the red white and yellow. I was wondering if there was some way I could hook it up to my computer and play the sounds of my ps2 out on my computer speakers. Like is there a way to combine the red and white into one audio input i could plug into my computer?
Or is there a way to change the red and white into the other plugs that could fit into the computer, because when I try to plug these in right now they are really loose and don't fit
