HowTo HP DV2000 compile alsa to resolve all issues (mic, jack, AC-power,auto mute)

[lexarrow]

I am currently running Ubuntu Studio on a HP Pavilion dv2025nr.

After this install you should have all sound features enabled.

This is a compile of alsa drivers 1.0.15rc3

1.Check your kernel version - in terminal window type:

`uname -r'

mine is 2.6.10-16-generic

2.Install these packages:

sudo apt-get install linux-headers-$(uname -r) build-essential libncurses5-dev libncursesw5-dev ncurses-term alsa-tools-gui gettext po-debconf debhelper quilt alsa-base libc6-dev

and uninstall these ones:

 sudo apt-get remove --purge alsa-base alsa-tools

be sure not to uninstall alsa-utils as it will uninstall your gdm too

3.Back-up your current configuration:

tar -zcvf original-drivers.tgz /lib/modules/`uname -r`/kernel/sound

4.Make a directory for alsa packages:

mkdir /home/user/alsa
cd /home/user/alsa

5. Get alsa packages:

wget ftp://ftp.alsa-project.org/pub/driver/alsa-driver-1.0.15rc3.tar.bz2
wget ftp://ftp.alsa-project.org/pub/lib/alsa-lib-1.0.15rc3.tar.bz2
wget ftp://ftp.alsa-project.org/pub/utils/alsa-utils-1.0.15rc1.tar.bz2
wget ftp://ftp.alsa-project.org/pub/firmware/alsa-firmware-1.0.15rc1.tar.bz2

6.Unpack archives:

tar xvf alsa-driver-1.0.15rc3.tar.bz2
tar xvf alsa-lib-1.0.15rc3.tar.bz2
tar xvf alsa-utils-1.0.15rc1.tar.bz2
tar xvf alsa-firmware-1.0.15rc1.tar.bz2

7.Install driver:
Note: 'sudo make clean' and sudo make mrproper are to clean out your previous drivers. If you are doing a fresh install, you don't need them.

cd alsa-driver-1.0.15rc3/
sudo make clean
sudo make mrproper
./configure --with-oss=yes --with-cards=hda-intel 
sudo make
sudo make install

9.Install alsa-lib:

cd alsa-lib-1.0.15rc3
sudo make clean
./configure
sudo make
sudo make install

10.Install alsa-utils:

cd alsa-utils-1.0.15rc1
./configure
sudo make clean
sudo make 
sudo make install

11.Install alsa-firmware:

cd alsa-firmware-1.0.15rc1
./configure
sudo make clean
sudo make 
sudo make install

12.double-click Volume control (the speaker next to the clock), then Edit->Preferences and check all the boxes (you should have 8 boxes : Master, PCM, LineIn, IEC958, Digital, Ext Mic, Int Mic, Int Mic (yes 2 times Int Mic). Close Preferences.

13.Go to Switches tab and check LineIn

14.Go to Recording tab and be sure both mic and speakers are not muted.

15. Go to Playback tab and be sure Master,PCM, and Ext Mic are not muted and BE SURE IntMic IS MUTED!

16. In a terminal, login as root and type:

 /etc/init.d/alsa-utils stop

17. Type the following command:

/usr/sbin/alsaconf

When it asks you, choose the 'hda-intel' card and then to save the changes to the files

18.Type:

 /etc/init.d/alsa-utils start

You should be done! If yo still don't have sound restart and it will be ok !

Note: 1. Every time you update the kernel, you have to recompile the driver
2. There is still an issue unresolved, the 'no sound after a windows session ' and can be fixed by unplugging the power cord before booting Ubuntu. If it doesn't work, reboot again with no power cord.

There's no solution for the 'no sound after Windows yet, but:

2.1 If you are in Windows unplug the AC cable and plug it back after you logged into Ubuntu.
2.2 If you are already on Linux after a Windows session and you didn't follow point 1.1estat, Unplug the AC cable, then SHUTDOWN , not restart the computer. Start it again manually and plug the cable back after you logged into Ubuntu

This way you should have sound every time you follow one of these 2 steps

Special thanks to these 2 articles: 1 and 2

Hope it works for you too!
