7.1 onboard sound speaker question

[G Evans]

I just installed a new motherboard with on board 7.1 channel sound but it
seems the only channel to get sound from a passive or nonamplified speaker
is the front jack, plugging the passive speakers into any of the other
jacks, rear , side sub or middle produces no sound. Yet if I plug my stereo
amp into these other jacks I get sound to the speakers. Is this just a sound
card problem?
Does this mean that the front jack is amplified internally only and the
others are not and therefore require one of those cheap computer surround
sound systems with the crappy speakers in them?

The motherboard audio outputs AND soundcards ONLY put out a LOW-LEVEL audio
signal that must be passed thru an audio Amplifier to raise it to a high
level audio signal that a non-powered speaker can use.
The HEADPHONE jack on the front of the computer is slightly amplified for
use by headphones only.
Bottom line: computers require the use of POWERED speakers, not passive.
