Reboot. If you're still missing the devices, try reinstalling the drivers for your sound card.

Hi,
Do as Phaelax suggested, go to device manager and check for yellow or red exclamation marks. Right click on sound devise and click update driver, if no good click uninstall driver then reinstall from your driver CD or download the latest drivers for your setup and install them.
