Sorry for my bad english, i'll try to explain my problem! I have Windows 7 and this card, i installed drivers and my surround speaker works. but Woofer does not work? My SW/CEN jack is connected to Orange Connector on card, i have tried to connect FRONT speakers to orange connector and problem is same, one speaker does not work, seems with rear speakers! But i try to "Test" my speakers with sound test in control panel and ALL SPEAKERS WORKS! What is the prob?
