text: yes you can. depending on your stereo. if your stereo has audio jack holes, one white and one red, you can purchase an adapter at radio shack that has 2 female audio jack holes on one end, and on the other end has a headphone plug, and simply plug it into your PCs speaker jack. i have the same thing hooked up at my house. i don't know if some sound cards have built in red and white audio jacks but you can try and look to see if there are some out there. also if your sound card or any other kind (I'm not sure) has a fiber optic digital line in, and your stereo has one, then you can do it that way. hope that helps, if you need i can send you a pic of what the connector looks like.
