download the lattest ALSA drivers from ftp://ftp.alsa-project.org/pub/driver/alsa-driver-1.0.20.tar.bz2.

extract the file, go to the folder & execute the following -

./configure
make
make install.

now open /etc/modprobe.d/alsa-base and try it with following lines-
options snd-hda-intel model=auto
options snd-hda-intel model=lenovo
options snd-hda-intel model=laptop-eapd
options snd-hda-intel model=3stack

reboot & see.
