I made this guide ti give more information to help me solving this problem
Hi,

In order to gather essential troubleshooting information about your sound card, please first follow this procedure:

Step 1: Open Terminal from "Applications->Accessories->
Terminal"

Step 2: Run the following 2 commands (copy/paste each command into the Terminal and then hit <enter> after each command)

wget -O alsa-info.sh http://www.alsa-project.org/alsa-info.sh

bash alsa-info.sh

When the alsa-info.sh script asks "Do you want to run this script? [y/n]", press y and then hit <enter> to make sure the script actually runs. Please send us the full terminal output after the script has actually run.

Step 3: Run the following command. The command STARTS with the word cat and ENDS with the word snd. So please copy-paste the ENTIRE command below into a Terminal, press enter, then enter password when sudo asks for password, then press enter again.

cat /proc/asound/cards; sudo aptitude install gnome-alsamixer asoundconf-gtk alsa-utils; asoundconf list; aplay -l; sudo lshw -C sound; ls -lart /dev/snd; cat /dev/sndstat; lspci -nn ; lsmod | grep snd

Step 4: Please post results (copy/paste terminal output) on this thread

Step 5: Please also report on this thread if you cannot hear sound through the speakers, the headphones or cannot hear sound on both.

Step 6: Please also specify the exact model and make of your PC (if possible) on this thread

Step 7: If you are using a dual boot system (with Windows and Ubuntu installed on separate partitions),
then make sure to set the sound volume in Windows to a high level before booting into Ubuntu.
Also make sure to use the special function keys in Windows to make sure the loudspeakers are physically switched ON and working properly in Windows before installing and testing Ubuntu. This step is necessary with certain Toshiba Tecra laptops.

Step 8: Experiment with the audio settings in gnome-alsamixer and asoundconf-gtk until you get sound (hopefully)

Step 9: In System/Administration/Users and Groups , make sure that your user and the root user are members of the following 5 groups:

pulse

pulse-access

pulse-rt

audio

video

Step 10: Run the command gnome-volume-control and set the Sound Theme to "No sounds" (Sound Theme is also accessible via System > Preferences > Sound)

Step 11: Try connecting headphones to different audio jacks/ports on the backpanel of the sound card until you hopefully hear sound

Step 12: If you happen to have two soundcards installed in your pc, one integrated into the motherboard and one inserted into a PCI slot, then try removing the PCI audio card, reboot your pc and retest sound using only the motherboard's soundchip.

Thank you mark i 've done what you said and i did what you wrote in https://answers.launchpad.net/ubuntu/+source/alsa-driver/+question/78023
so if anyone has any problems with the hp pavilion dv3510nr i did this part of the post
1. copy-paste the following command into the Terminal:

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

2. and add these lines to the end of the file:

# Keep snd-pcsp from being loaded as first soundcard
options snd-pcsp index=-2
alias snd-card-0 snd-hda-intel
alias sound-slot-0 snd-hda-intel
options snd-hda-intel model=hp-dv5
options snd-hda-intel enable_msi=1

3. Then navigate to System>Preferences>Sound and change everything to ALSA

4. reboot and retest sound

Thanks Mark Rijckenberg, that solved my question.

Daniel, this is not available in 9.10. did you simply skip this step?
