Ubuntu 9.10 Karmic Koala / Intel Audio Device – Mic working and no ‘popping’ sounds …

Here is the device that we are dealing with:

00:1b.0 Audio device: Intel Corporation 82801H (ICH8 Family) HD Audio
Controller (rev 03)
Codec: Conexant CX20549 (Venice)

And the Operating System is: Ubuntu 9.10 (Karmic Koala)

NUMBER 1: To get the sound and internal mic working do the following:

Add the following two lines to your sources.list file (sudo gedit /etc/apt/sources.list)

deb http://ppa.launchpad.net/c4pp4/cx20549/ubuntu karmic main
deb-src http://ppa.launchpad.net/c4pp4/cx20549/ubuntu karmic main

Then add the PPA key with the following command:

sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys 42FA88E8

Then refresh the package list:

sudo apt-get update

Then upgrade the packages:

sudo apt-get upgrade

Once finished reboot your computer and your DONE!

NUMBER 2: Get rid of the popping sounds

In your Terminal do:

sudo gedit /etc/modprobe.d/alsa-base.conf

and change the setting:

options snd-hda-intel power_save=10

to

options snd-hda-intel power_save=0

Reboot!
