Ubuntu

Realtek AC'97 ,No sound

Asked by Kamalesh

Hello All,

  My name is Kamalesh,I'm new to Ubuntu community as well as to Ubuntu itself. I have Ubuntu 8.10 installed in my notebook.

Make : Compaq
Model: B1803TU
Sound Card: Realtek AC 97
Processor:Intel Centrino

My problem is, I never got my sound working. Right now i think i dont have any sound drivers installed
since i repeatedly tried installing the latest alsa project, by reading different forums and all. Installation
failed because of compiling errors and all. It said some of the lib files etc. were missing.

If anyone would help me, please be aware that im a complete noob :).

Thank you for your kind help

OMG!!!!!!!!!!! IT WORKED AT LAST !!! :D I'm really really happy !!!

Ubuntu 8.10

All I had to do was :-
goto applications -> Sound and Video -> Volume Control.

Then goto edit -> preferences in the volume control. look for "external amplifier" (or just check everything like i did. there is nothing wrong with it. Just that the volume control gets cluttered.) Click close to accept changes. Click the "switches" tab and uncheck "external amplifier", at this point my speakers began to blare since i had all the sound slider's maxed and a video playing... Them blaring wasn't a problem it was the suddeness. I almost needed a clean pair fo shorts. For laptop speakers they are pretty darn loud. Hopefully this will help someone out there.

*Not If u dont have 'Volume Control' in Sound&Video, Right Click on "Applications" ->Edit Menus->(find Sound and Volume in the left menu)-> [check]Volume Control

OR

Just Right Click on the volume control (small speaker) icon near the clock. ->Open Volume Control->Preferences
->[check]External Amplifiers Switches , then just go to Volume Control and [UNCHECK] External Amplifiers

If that didnt work, then download and install the alsa project from:
www.alsa-project.org/

    * alsa-driver-1.0.18a
    * alsa-lib-1.0.18
    * alsa-utils-1.0.18
    * alsa-tools-1.0.18
    * alsa-firmware-1.0.17
    * alsa-plugins-1.0.18
    * alsa-oss-1.0.17

Download all those and follow :
##################

Open a terminal window hit return after each line of codealso I had to hit "y" for yes to allow some changes

Create a folder called "alsa" in your home directory with the command;-

Code:

mkdir ~/alsa

Move the downloaded files to this directory.

Execute the following commands from within a terminal.

Code:

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

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

cd ~/alsa

tar -xvf alsa-driver-1.0.18a.tar.bz2

tar -xvf alsa-lib-1.0.18.tar.bz2

tar -xvf alsa-utils-1.0.18.tar.bz2

tar -xvf alsa-oss-1.0.17.tar.bz2

cd alsa-driver-1.0.18a

./configure --with-cards=hda-intel

make

sudo make install

cd ../alsa-lib-1.0.18

./configure

sudo make install

cd ../alsa-utils-1.0.18

./configure

sudo make install

cd ../alsa-oss-1.0.17

./configure

sudo make install

Reboot

Hope this helps
