You may have inadvertantly installed the wrong drivers: Creative doesn\'t have a good way of distinguishing between some of their software/drivers.
Make sure to get the drivers that are for the Live! Value card and not the ones for the Live! 5.1, etc... I had this problem, too. I have both cards (5.1 in my machine, Value in my wife\'s machine). I had to delete all of the Creative drivers from the machine, reboot, then reinstall the correct drivers, reboot, then all worked fine.
If you don\'t delete the drivers, installing the correct ones won\'t work!!!!!
