Ubuntu 9.10 can not recognize intel sound card

At my LG P1 with an Intel sound card (Realtek ALC888 Intel 82801), after upgrading to Ubuntu 9.10 Karmic Koala, i had no sound.
The sound card wasn't even detected!

After running Google for a FEW hours, i discovered how to put the sound working without had to:
qaz@blue:~$ sudo alsa force-reload
or any other command.

Step1:
$ sudo apt-get remove sl-modem-daemon
Step2:
$ sudo apt-get install linux-backports-modules-alsa-karmic-generic
Step3:
$ sudo gedit /etc/modprobe.d/alsa-base
And add:
options snd-hda-intel model=lg # for other brands: search google with "options snd-hda-intel model="; try laptop; And/or visit this page.
Then reboot!
