Sound/Speaker Connections?

[Artreid]

A friend is trying to setup speakers on a computer he was given and has not
been able to get any sound from it. I believe there are (at least) two types
of speaker system, one type requires a power source to power the speakers
and another (probably older) does not?
- Can anyone tell me what these two systems are called? (I believe there
called Wired and Unwired) or something like that)?
- How does one determine what speaker system will work on your computer? (I
believe the newer computer use speakers driven by a power source)?

The two type of speaker system might be labled as "amplified" and "non-
amplified" systems. The first one has a component which will "boost"
the sound volume automatically while the second relies on the sound
card's amp to control the volume.

You need to make sure that the speakers are connected to the "front"
audio / speakers out jack, usually "green" colour.
