Ditto Noriaki's post. Yes, you'll get sound out of it. If you have decent speakers it might even sound ok. However, a separate PCI sound card will not only sound a lot better, it will give you much more flexibility with tuning the sound. You'll also use a lot less of your CPU, which is a good thing. For a basic setup (surfing, email, typing letters) onboard sound is a fine option. But for gaming, MP3, etc, you need a dedicated card.
