I just got a SB Live! 5.1 Sound Card, and I have Cambridge Soundworks (a division of Creative) speakers. However, whenever I load up WinXP, it only gives me 2 speaker support when I have all 4 connected. Only until I go to my mixer settings and re-set the value to 4.1 or 5.1 will all 4 speakers work. Is there a way to make them work when WinXP is started?
