In my last installation of debian (Squezee unstable), i dont have problems with the sound

But with my new installation of squezee, when i tried to activate the volume control (With the gnome applet), the system told me this (Aprox):

Volume control cant find devices to control. You dont have the correct addons of Gstreamer or sound device configurated
This is my computer data:

Motherboard = Gygabite M68M S2P

lspci | grep -i audio

I tried with "alsaconf", but this command doesnt exist in the new debian, with the correct command, i have this:

alsactl init
