The sound in the HP dv 2000 is a little tricky with Ubuntu/Linux.

The dv2315nr is equipped with a NVidia sound chipset.

I manage to make it worked with this post on the Ubuntu Forum:

1-Install these packages:

sudo apt-get install linux-headers-$(uname -r) build-essential libncurses5-dev libncursesw5-dev ncurses-term alsa-tools-gui gettext

2-Backup your current configuration:

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

3-Make a directory for ALSA packages:

mkdir /home/user/alsa

4-Get ALSA Packages

wget ftp://ftp.alsa-project.org/pub/driver/alsa-driver-1.0.14.tar.bz2
wget ftp://ftp.alsa-project.org/pub/lib/alsa-lib-1.0.14a.tar.bz2
wget ftp://ftp.alsa-project.org/pub/utils/alsa-utils-1.0.14.tar.bz2
wget ftp://ftp.alsa-project.org/pub/firmware/alsa-firmware-1.0.14.tar.bz2

5-Unpack Archives:

tar xvf alsa-alsa-driver-1.0.14.tar.bz2
tar xvf alsa-alsa-lib-1.0.14a.tar.bz2
tar xvf alsa-alsa-utils-1.0.14.tar.bz2
tar xvf alsa-alsa-firmware-1.0.14.tar.bz2

6-Install driver:

cd alsa-driver-1.0.14/
sudo make clean
sudo make mrproper
./configure --with-oss=yes --with-cards=hda-intel
sudo make
sudo make install

7-Install Alsa-lib

cd alsa-lib-1.0.14a
sudo make clean
./configure
sudo make
sudo make install

8-Install Alsa-utils (it appears that this one is not necessary)

cd alsa-utils-1.0.14
./configure
sudo make clean
sudo make
sudo make install

9-Install Alsa-firmware

cd alsa-firmware-1.0.14
./configure
sudo make clean
sudo make
sudo make install

10-Restart and you should be done!

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.
3. If you still don’t have sound try this:

I. Boot up Ubuntu WITHOUT power cable.
a. upgrade kernel if you would like.
b. edit /etc/modprobe.d/alsa-base: options snd-hda-intel index=0 model=3stack-dig
II. play some sound or something (make sure it works)
III. Rather than restart send it into hibernate.
IIII. after hibernation is complete, bring it back up.
it should crash.upon crashing, alt+ctrl+del
reboot into ubuntu.
