does your monitor have speakers? if not does your monitor have audio out?
if the answer to both of those is no, then I suggest you look elsewhere, since in order for you setup to run properly you will need to spend around $100 for a digital to analog adapter.
If the answer to either of those is yes, use an HDMI cable, to hook it up to your monitor. If monitor doesn't have hdmi, use the ports that it has available.
you didn't exactly specify the model of your monitor so I can't check online what it is
