Sound does not work on Ubuntu

[anselmop]

Hi, folks. I have just installed Ubuntu 8.04 on my N200 7369-AAP and I can't hear any sound. The volume controller on Gnome shows normally, as if the sound card was working. Have any of you come across the same problem? I would be grateful for any help.

Can you open the sound settings up? This is the screen where you can choose the sound system (ALSA, OSS, etc.). Try forcing it to ALSA instead of Pulseaudio, that helped for mine.

I think the problem is caused by a lack of hardware drivers in the distribution of Debian on which Ubuntu and other current distributions of Linux are based.

I have tried the KDE desktop based LiveCDs of Kubuntu 8.04.1; and SimplyMEPIS 7.0, and both have no sound at all on my 3000 n200 0769-A64. Kubuntu uses KDE 4.0, and SimplyMEPIS uses KDE 3.5. Neither have PulseAudio as an available audio output option.

In Ubuntu 8.04.1, the only audio output choices I have are:

HDA Intel (ALSA Mixer)

Realtek ALC861-VD (OSS Mixer) 

Playback: ALSA PCM on front: 0 (ALC861VD Analog) via DMA (PulseAudio Mixer)

Irrespective of which audio output device I select, I get no sound at all from my notebook under these distributions of Linux. 

I cannot see how to change which sound system is being applied to which audio output device in Ubuntu. 

Before testing in each case I made sure that the volume sliders were set to maximum, and that the devices were not muted. 

I've not tried a current LiveCD of Linux that is not based on Debian.

Hi folks, I have a 3000 n200 0769brg and the following worked for me on both mint and Ubuntu so prob ok on debian based distro. Also I think you need multiverse&universe or your distros repository equivalents enabled

. 

I take no credit for finding the solution offered here, but instead, offer eternal thanks to "jamdess" and "Apprenti_chercheur" for their excellent knowledge of Linux..
 
The first step is to download the latest ALSA driver and associated files from:- http://www.alsa-project.org/
At the time of writing  the following versions were available, I suggest you download all of them:-

alsa-driver-1.0.17
alsa-lib-1.0.17
alsa-utils-1.0.17
alsa-tools-1.0.17
alsa-firmware-1.0.17
alsa-plugins-1.0.17
alsa-oss-1.0.17
pyalsa-1.0.17

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

cd alsa-driver-1.0.17
./configure --with-cards=hda-intel
make
sudo make install

cd ../alsa-lib-1.0.17
./configure
sudo make install

cd ../alsa-utils-1.0.17
./configure
sudo make install

cd ../alsa-oss-1.0.17
./configure
sudo make install

Edit your alsa-base file
Code:
sudo gedit /etc/modprobe.d/alsa-base
Add the following line to the file

Code:
options snd-hda-intel position_fix=1 model=lenovo
Save the file and reboot the computer and hopefully you should now have sound.

Hope this helps

Regards

Rob

Sorry forgot to add:

open terminal:

code:

alsamixer (hit return)

you can now adjust the volumes once all previous instructions followed

Cheers!

Hi, I've got Ubuntu 8.04 with Gnome running on a 3000 N200 0769-K2G, and I just went with the following from Rob's post, and didn't need to re-compile alsa, the Intel chipset support was already there.

Thanks Rob.
