Sound issue Ubuntu 7.10

I installed Ubuntu 7.10 on my new Zepto 3215W and all hardware worked except the audio. As written on the Zepto site, you have to install new ALSA drivers.

I've solved the problem by following the steps below:

- - -
Install dependencies:
sudo apt-get install libncurses5-dev
build-essential ncurses-dev gettext linux-headers-`uname -r`

Download the files needed (this is version 1.0.15rc2):
ftp://ftp.alsa-project.org/pub/driver/alsa-driver-1.0.15rc2.tar.bz2
ftp://ftp.alsa-project.org/pub/lib/alsa-lib-1.0.15rc2.tar.bz2
ftp://ftp.alsa-project.org/pub/utils/alsa-utils-1.0.15rc1.tar.bz2

Notice: ALSA 1.0.15 is released, so go download that instead.

I save mine on separate home-partition first (in case of reinstall) to a
directory called ~/ALSA/1.0.15rc2 and then I do the following:
sudo mkdir -p /usr/src/alsa
cd /usr/src/alsa
sudo cp ~/ALSA/1.0.15rc2/* .
sudo tar xjf alsa-driver-1.0.15rc2.tar.bz2
sudo tar xjf alsa-lib-1.0.15rc2.tar.bz2
sudo tar xjf alsa-utils-1.0.15rc1.tar.bz2

Then compile (I'm not sure if the --with-oss=yes is needed):
cd alsa-driver-1.0.15rc2/
sudo ./configure --with-cards=hda-intel --with-oss=yes
sudo make
sudo make install
cd ../alsa-lib-1.0.15rc2/
sudo ./configure
sudo make
sudo make install
cd ../alsa-utils-1.0.15rc1/
sudo ./configure
sudo make
sudo make install

Then edit alsa-base in /etc/modprobe.d:
sudo nano /etc/modprobe.d/alsa-base
And add the following line at the end:
options snd-hda-intel model=acer

Then restart the ALSA deamon and ALSA will find your audio hardware. You can also reboot your laptop if you like.

Notice: If you install a new kernel you'll have to do it all over again.
