I just finished building my PC yesterday and I finished installing everything today. I loaded up firefox and went to youtube, strangly, no sound came out of my speakers when I clicked on a music video. I went to see if the drivers or w/e was installed. Weird, it had Realtec AC97 Audio under the SOUND, VIDEO, AND GAME CONTROLLERS. I checked for any updates but there were none. Please help! I would really not want to go and buy a sound card. Here is my MOBO
