no sounds on web or inside applications. intel card.

Could you run the following command in a terminal and post the output please ?
grep Codec /proc/asound/card0/codec#*

You should get something like this :
$ grep Codec /proc/asound/card0/codec#*
/proc/asound/card0/codec#0:Codec: Realtek ALC268
/proc/asound/card0/codec#1:Codec: Generic 11c1 Si3054

Could you also give the brand and model of your computer ?

hello

I am very thankful to you for your concern. I just logged in to my linux,
ubuntu and my sound seems to be working. I dont know what would not work
but finally it is fine.

Anyways here is what oyu asked for, and it does not look the same as u
expected it to be,

lakshman@lakshman-laptop:~$ grep Codec /proc/asound/card0/codec#*
Codec: Conexant CX20549 (Venice)
lakshman@lakshman-laptop:~$

Thanks lakshman

You just need to install alsa drivers 1.0.15rc3 (Gutsy shipped with alsa driver 1.0.14 by default).
It's really simple to do : You just need to install the linux backports module packages by running in a terminal the following command :
sudo apt-get install linux-backports-modules-generic
And then reboot.

Keep me posted.

Hi,

The command "grep Codec /proc/asound/card0/codec#*" gives you the real name of the sound card.
You have a Conexant CX20549 (Venice). I have a Realtek ALC268.

Could you confirm me that you have upgraded your alsa drivers by running sudo apt-get install linux-backports-modules-generic and rebooting ?

After that could you try this :
In a terminal, run this command to edit the file /etc/modprobe.d/alsa-base:
sudo gedit /etc/modprobe.d/alsa-base
and search the following line :
options snd-hda-intel
And modifiy it (or add it) so that it looks like :
options snd-hda-intel disable_msi=1
Then reboot and test if sound works.

Keep me posted.
