You know, special thanks to a guy in freenode who helped me with this problem, nick 'el_choya_II' a real guru.
Well first step:
I unistall all packages about alsa, alsa-utils, alsa-oss and alsa-lib.
Reinstall all packages (I recommend you that install all packages with your manager i.e. apt-get, slapt-get, etc)
Third Step: (as root)
# cd /usr/src/linux
# make xconfig
And you'll see a graphic tree of the kernel configuration, you have to go to Sound -> Advanced Linux Sound Architecture and you have to see if it's marked with a point or a (*) like that.
Now we have to go to PCI Devices -> Intel HD Audio, we have to see if Intel HD Audio is as module a dot on xconfig and on menuconfig is M.
Now try as root:
# modprobe snd
# modprobe snd-hda-intel
If everything is ok without error up to this moment then we have to add those lines in /etc/rc.d/rc.modules and save the changes with pico or vi
Then, now ...
(remember.. install alsa-utils hehe 'cause you'll need it to do this).
and voilá! you'll get audio..
try with audacious or with amp..
thank you I did that and it worked for me
