For some strange reason my sound card doesn't work.  The device manager says its working fine, but the sounds and audio devices panel says there is no audio device installed and when I try to play any sounds it doesn't work and the system says the sound card may be in use, but it's not.  How can I fix this problem.  I went through the troubleshooting guide and that didn't help any.  I'm about ready to give up and call creative labs tech support (I have a sound blaster live).
