Well, then you need a better salesman. The thing's _got_ sound. But this is _not_ a media center, so don't act as if it was one. It's a home computer, a cheap one at that, and I think it compares well to other cheap computers out there.
Btw.: Show me the 499$ computer with digital audio out. Show me the 499$ media center. Or rather, know what? Don't.
