Unless you added a video capture card, the majority of stock PC's do not come with one as an option. The S-Video jack on the PC is most likely an output for extended desktop monitor.
Video capture cards will typically have both the video & corresponding audio inputs for the sound.
You can get an internal card and install it into your PC or get a USB interface that will work with both the PC or the laptop.
