Ubuntu

Codec: Realtek ALC260 Mixer: Realtek ALC260 - ALC260 Analog (DUPLEX) Audio device [0403]: Intel Corporation 82801G (ICH7 Family) High Definition Audio Controller [8086:27d8] (rev 01) - sound not working on headphones and speakers on HP Compaq dc7600 SFF Base Unit in Ubuntu 9.04

Asked by AJ C.

I installed Ubuntu on my HP Pavillion dv6000 laptop several weeks ago, abnd has since worked a charm.

I have recently upgraded my desktop pc to Ubuntu also, but I have discovered that there is no sound whatsoever.

After much use of the Synaptic Package Manager in a futile attempt to unearth the answer to my problem, I relocate my quest here.

I enquire again; Could anyone have the answer to my seemingly "n00b" problem?

Thanks again, and excuse the long words ;)

Did I mention that my desktop machine, the one with the problem, is a HP Compaq dc7600 SFF Base Unit?

OK, thanks in advance,

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 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.

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

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

http://ubuntuforums.org/showthread.php?t=789578&highlight=audacity

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

Each combination of audio codec, audio mixer and audio device name requires a very specific configuration in the alsa-base.conf file, if the audio chipset does not work out-of-the-box.

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 in gnome-alsamixer.

If sound still does not work, try upgrading ALSA to the newest version, reboot and retest sound.

ALSA upgrade procedure is here:

Kind regards,

Mark

I cannot hear a sound through headphones and speakers, and no sound is being recognized via the microphone, although they all work perfectly with my HP Pavilion laptop, also running Ubuntu 9.04.

Hi,

Please keep the C-Media USB Headphone Set unplugged and disconnected from your pc while performing the following procedure.

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

 pulse
 pulse-access
 pulse-rt

Then please try this procedure:

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 /etc/modprobe.d/alsa-base.conf 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-dc7600
options snd-hda-intel enable_msi=1

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

4. reboot and retest sound on the speakers

5. If sound still does not work, then replace hp-dc7600 with one of the following model options:

 ALC260
   hp HP machines
   hp-3013 HP machines (3013-variant)
   hp-dc7600 HP DC7600
   fujitsu Fujitsu S7020
   acer Acer TravelMate
   will Will laptops (PB V7900)
   replacer Replacer 672V
   basic fixed pin assignment (old default model)
   test for testing/debugging purpose, almost all controls can
   adjusted. Appearing only when compiled with
   $CONFIG_SND_DEBUG=y
   auto auto-config reading BIOS (default)

6. You will have to reboot and retest sound after every model option change to the alsa-base.conf file

Regards,

Mark

I believe that the alsa-base.conf file should contain the following model option for the HP Compaq DC7600: basic

So the last part of the alsa-base.conf file should look like this:

# 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=basic
options snd-hda-intel enable_msi=1

-> See this URL for details:

Can you help with this problem?
