Whats the difference between onboard sound and a soundcard?
In an ideal world, there would be no difference. Alas, we do not live in an ideal world! Often onboard sound has been added with little regard to anything but cost. This often means that it performs poorly. Poorly could mean muffled sound, poor bass, a high level of noise or a blatent inability to do what it’s meant to do. Often onboard sound has less in the way of features compared to a soundcard. Some soundcards also suffer from the same problems as onboard sound, but these are generally the very cheap generic parts. Generally, the more expensive a soundcard is, the better it performs.
