Creative Sound Blaster Z rear speakers problem...

[NomNom]

This is the first time I encountered this problem, and happened after I installed onboard speakers driver as I usually use it for my headphones (since it’s easier).

The problem is that when I test out the speakers everything is fine except for the rear speakers which on has bass from subwoofer. Now if I turn off rear speakers from sound blaster control panel then test out the rear speaker by clicking on the rear speaker the speakers would work.

I’ve matched the speaker configuration (5.1) on sound blaster control panel with the windows audio control panel so they both has the same settings. If I turn on the rear speakers on the windows audio control panel then it’ll work. It won’t show enabled in the sound blaster control panel... but even enabling it from windows control panel i don’t hear anything from the rear speakers...

I would appreciate any help guys.
