can you try putting the rear jack into the front jack instead, and check if there's any sound?
When i put the rear and front input accordingly, centre, subwoofer, and front speaker produces sound.
When i put the rear input into front input and vice versa, only the rear speaker produces sound.
I change the connection at the control box, and not at mobo's sound card connector.

start > control panel > sound > select your soundcard > configure (left bottom) > choose 5.1 speaker > finish.
start > control panel > sound > speakers/digital audio (at playback) > speakers > configure (left bottom) > choose 5.1 surround > press test > all speakers are functioning well (produces sound).
But when playing youtube or original cd song the rear speakers did not produces sound. How come?
