Star Wars Knights of the Old Republic II: The Sith Lords

What's the benefit of using powered vs. amplified speaker systems with the game?

If you have powered speakers and have both line-out and speaker-out jacks on your sound card, try plugging your speakers into the line-out jack. Most sound cards speaker-out jacks have an amplified signal and may cause static or popping on your amplified speakers. Switching to your line-out jack may greatly improve the sound quality.
