No device in /dev for my sound card

[Kardwik.Karlov]

I've installed Gentoo, X Kde and Gnome but when i try to install Alsa, I can't find any file device in /dev ( /dev/dsp or /dev/sound directory )
My sound card is a Creative Labs Platinum Ex.

Thanks

This usually happens if you don't have the right drivers compiled into your kernel for your sound card, or if you compiled them as modules and the modules aren't loaded.
