you will have some sort of sound device, weather it be on-board or an internal add-on.
the fact that an analysis does not show one says that it may be malfunctioning.
you could first try to uninstall the drivers for the sound device and then install them again.
if you have an internal removable card, you can pull it out and try any on-board sound device you may have.
or if you don't have an on-board sound device, just re-seat the internal sound card.
lastly, for about $30, Creative has a 7.1 sound card.
these are the things I would try if I was having this problem.
