I recently purchased a new monitor (this should have nothing to do with it, but it might, its an LCD with a DVI link to my graphics card), but anyway, after rebuilding my comp, i have no sound. My sound worked fine before the rebuild, and all wire connections are fine. My computer recognizes the card (Sound Blaster Audigy 2 ZS) and all the drivers are re-installed and it says that all my sound devices are working properly. I have tried all the PCI slots, and nothing. My computer does not recognize a sound device anywhere else other than the device manager. In the control panel, the sound set-up says there is no sound device. Any ideas what to do??
