Ubuntu Audio Problems on an ACER 5570WNXCi Laptop

Last summer, after installing ubuntu 7.04 (feisty fawn) on my laptop. I can’t get the audio running. Prolly thedevice driver was not detected or so. I don’t know exactly what happened. But i did a little research though. I saw this on a post in ubuntu forums but i deleted unnecessary instructions. 🙂

HDA Intel Sound:

#1 First, download the necessary libraries 

sudo apt-get install build-essential ncurses-dev gettext

#2 Install the kernel headers

sudo apt-get install linux-headers-`uname -`

#3 Download these drivers from the ALSA Project (driver, library, and utils) to a directory (eg. ~/downloads).

In the following we assume that the latest version is 1.0.14rc4. Please change his in accordance with the one you downloaded from the Alsa projectsite.

#4 Set-up installation directories

sudo mkdir -p /usr/src/alsa
cd /usr/src/alsa
sudo cp ~/downloads/alsa* .
sudo tar xjf alsa-driver-1.0.14rc4.tar.bz2
sudo tar xjf alsa-lib-1.0.14rc4.tar.bz2
sudo tar xjf alsa-utils-1.0.14rc4.tar.bz2

#5 Compile and install alsa-driver

cd alsa-driver-1.0.14rc4
sudo ./configure –with-cards=hda-intel
sudo make
sudo make install

#6 Compile and install alsa-lib 

cd ../alsa-lib-1.0.14rc4
sudo ./configure
sudo make
sudo make install

#7 Compile and install alsa-utils 

cd ../alsa-utils-1.0.14rc4
sudo ./configure
sudo make
sudo make install

Note that you must have the curses library installed to be able to compile alsa-utils. You can install it with this command from a terminal:

sudo apt-get install libncurses5-dev

#8 Reboot

It worked for me, why don’t you try it with yours. 🙂
