I bought a set of Logitech Z506 speakers (don't need no audiophile discussion here) and a diamond multimedia 5.1 soundcard.

For some reason, the front right and left speakers work but the 2 rear, center, and subwoofer don't seem to work. The speakers are used so nut sure if broken or what..

First, your source needs to have 5.1, which means videos on YouTube or most music programs are only going to use the front left/right speakers.

Secondly, make sure Windows knows you have 5.1 now. Go into your Control Panel, Sound, and then Configure your speakers and make sure you tell Windows you're using a 5.1 setup. You might also need to go into the Diamond sound card drivers to set this same thing.

Configure to 5.1 in Windows Control Panel, it will test all the speakers.
