Report "During the speaker configuration in control panel (windows 7 ultimate) the center and subwofer make no sound, but windows recognizes that noise is being made represented by the green bar rising. However, when I listen to music or play games, both the sub and center speaker work just fine. I think this problem is also related to ventrilo application. When I have my speakers configured to stereo (2 speakers) I can hear people over my speakers, however when I set it to 5.1 surround I cannot hear them. Please advise"
