Laptop No Sound

[Whitecloud]

I use a Gateway MX 6920 Laptop. I did a clean install, and ended up with No Sound. Tried one more clean install same thing, No Sound.

I've tried downloading different drivers, but still nothing No Sound.

Now in My Computer under Manage I have 6 Yellow Question Marks (?)

? Other Devices

? Mass Storage Controller
? PCI Device
? SM Bus Controller
? Video Controller
? Vedio Controller (VGA Compatable)

I tried Upgrading the drivers on each. Nothing

I have removed these same ones, rebooting and installing the same. Still No Sound.

Anyone have any solutions to correct this problem.

MX 6920

Thanks for any help. Ron..
