Well, I unfortunately found out that there is not a driver for my sound card from ALSA. Is there any way that I can make a request for a driver for my sound card? Or is there another way to make my sound work?

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 commands (copy/paste each command into the Terminal and then hit <enter>)

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 commands (copy/paste each command into the Terminal and then hit <enter>)

cat /proc/asound/cards
asoundconf list
sudo aptitude install gnome-alsamixer asoundconf-gtk
aplay -l
cat /dev/sndstat
lspci -nn
lsmod | grep snd

Step 4: Please post results (copy/paste terminal output from each command) 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: 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. Make sure to enable the loudspeakers using the functional keys in Windows before booting into Ubuntu. This step may be necessary for your HP Pavilion laptop.

Step 7: Experiment with the audio settings in gnome-alsamixer and asoundconf-gtk until you get sound (hopefully)

Step 8: 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

=======================================================================================

Please also read the following pages

http://www.ubuntugeek.com/sound-solutions-for-ubuntu-904-jaunty-users.html

http://doc.ubuntu-fr.org/audio_intel_hda (check for correct /etc/modprobe.d/alsa-base.conf options at bottom of this page)

https://help.ubuntu.com/community/SoundTroubleshooting

for some initial suggestions.

You should add the following string to the /etc/modprobe.d/alsa-base.conf file

options snd-hda-intel model=YOUR_MODEL

Valid model names (that replace YOUR_MODEL) depending on the codec chip, can be found at

http://kernel.ubuntu.com/git?p=ubuntu/ubuntu-jaunty.git;a=blob_plain;f=Documentation/sound/alsa/ALSA-Configuration.txt

If you do not know your codec chip name, you can execute the following Terminal command to find out:

cat /proc/asound/card*/codec* | grep Codec

Make sure to set all channels to high volume levels in gnome-alsamixer.

Make sure all the different speakers (including 'Front', 'Master', and 'PCM") are NOT muted and NOT set to low volume levels.

Kind regards,

Mark
