Install Sound Card Lenovo Y410 Series in Ubuntu 8.04

Recently i managed to replace my old IBM Thinkpad Laptop with
Lenovo Y410 series laptop, now i never had any kind of hardware
related problem on my old Thinkpad. But sadly after installing
Ubuntu 7.10 , Fedora Core 8 on my Lenovo laptop i was terribbly
disappointed to find my audio hardware not working . So well my
search began searching all kind of forums for my problem and
finally i found following the steps below made my audio hardware
work : -

eed additional repositories to be installed or some to be enabled in Synaptic package
manager so before trying out steps given below ensure that repositories in order.

Launch Synaptic Package Manager (System -> Administration -> Synaptic Package Manager ) , then in Synaptic package manager go to (Settings -> Repositories ) you will find window like this . Ensure that all the check boxes are marked leaving source code(if you want to you can enable this also but you are not going to need this unless you are software developer) the dialog box should look like this .

- mark all Download from internet accept source-code

- mark officially support >> close and reload
After completing above step type in the following command in the terminal window : -

sudo apt-get install build-essential
and
sudo apt-get install po-debconf
and
sudo apt-get install debhelper
and
sudo apt-get install quilt
and
sudo apt-get install libc6-dev

After completing above steps we need to download the updated alsa-driver and compile and install it .

Type the following command in the terminal window chdir into your home directory and being the superuser( su ): -

wget ftp://ftp.alsa-project.org/pub/driver/alsa-driver-1.0.15.tar.bz2
and
tar -xvjf alsa-driver-1.0.15.tar.bz2
and
cd alsa-driver-1.0.15

and type the following command :

./configure
make
make install

and the following command in the terminal window

rm /lib/modules/2.6.22-14-generic/ubuntu/media/snd-hda-intel/snd-hda-intel.ko

and

ln -s /lib/modules/2.6.22-14-generic/kernel/sound/pci/hda/snd-hda-intel.ko /lib/modules/2.6.22-14-generic/ubuntu/media/snd-hda-intel/snd-hda-intel.ko

and add the following line at the bottom of file (/etc/modprobe.d/alsa-base) maybe using gedit (sudo gedit /etc/modprobe.d/alsa-base )

options snd-hda-intel index=0 model=fujitsu

also add the following lines at end of /etc/modules (sudo gedit /etc/modules)

snd-hwdep
snd-hda-intel

After completing above steps restart computer , and hopefully sound would be working though there are still some unresolved issue because of which sound works through laptop speakers only and not through line-out , but still it’s better than not being able to play sound .
