A listing of random software, tips, tweaks, hacks, and tutorials I made for Ubuntu

Sound Troubleshooting

This tutorial will try to help you hear sound again! Notice that there is a newer version of this guide available here: https://docs.google.com/document/d/1iTlJ8BfqXUjaHO__TEdlkvuqB1WLOkGaudngc5SFLMI/edit

If you don’t hear sound in flash, open up a Terminal window, and type in it:
sudo ln -s /usr/lib/libesd.so.0 /usr/lib/libesd.so.1
sudo mkdir -p /tmp/.esd/
sudo touch /tmp/.esd/socket

Preliminary Checks:

Make sure your speakers are on turned on, not muted, and on full volume
Make sure your speakers are plugged in correctly (usually plugged into a green jack)

Check 1: Check if the problem is the hardware or the software

Burn a LiveCD of any system (preferrably ubuntu), put it in your disk tray, and reboot. See if you can hear sound (by playing an audio file, or something). If you have windows, see if sound works there.
Success: You hear sound, go to Check 2
Failure: You do not hear sound.
This can be caused by 4 things:

  1. The LiveCD does not support sound correctly.
  2. Your BIOS disabled your soundcard. Reboot, and hit the key to enter your BIOS (usually Esc, Delete, F1, F2, F8, or F12). *TODO: Add more info*
  3. Your soundcard is broken. Replace it
  4. Your speakers are broken. Replace them

Check 2: Check if ALSA recognizes your soundcard(s)

Boot back into your normal system, open up a Terminal window, and type in it:

aplay -l

Success: You see your soundcard(s)
Type in the Terminal window:

sudo usermod -aG audio `whoami`

Log out, and log back in, then follow the alsamixer section, making sure everything is at full volume, and then test your sound using (you might have to run it a few times):

aplay /usr/share/sounds/alsa/Front_Center.wav

Success: You hear sound
Failure: You do not hear sound. Use this guide: http://idyllictux.wordpress.com/2009/04/21/ubuntu-904-jaunty-keeping-the-beast-pulseaudio-at-bay/

Reboot and then follow the alsamixer section

Failure 1: You see something similar to:

**** List of PLAYBACK Hardware Devices ****
ALSA lib conf.c:3643:(snd_config_update_r) Cannot access file /usr/share/alsa/alsa.conf
ALSA lib control.c:882:(snd_ctl_open_noupdate) Invalid CTL hw:0
aplay: device_list:249: control open (0): No such file or directory
ALSA lib conf.c:3643:(snd_config_update_r) Cannot access file /usr/share/alsa/alsa.conf
ALSA lib control.c:882:(snd_ctl_open_noupdate) Invalid CTL hw:1
aplay: device_list:249: control open (1): No such file or directory
ALSA lib conf.c:3643:(snd_config_update_r) Cannot access file /usr/share/alsa/alsa.conf
ALSA lib control.c:882:(snd_ctl_open_noupdate) Invalid CTL hw:2
aplay: device_list:249: control open (2): No such file or directory

Simply type in it:

sudo apt-get install --reinstall libasound2

Then follow the Alsamixer section
Failure 2: You see something similar to:

aplay: device_list:221: no soundcard found...

Type in the Terminal window:

sudo aplay -l

Success: You see your soundcard(s).
Type in the Terminal window:
sudo usermod -aG audio `whoami`
Reboot, and follow Check 2
Failure 2: Follow Check 3

Check 3: Check if your system recognizes your soundcard(s)

Type in the Terminal window:

lspci -nn | grep '04[80][13]'

Success: You see results, move on to Check 4
Failure: You do not see results, which means that Ubuntu does not detect your soundcard. *TODO: Add more info*

Check 4: Check if your soundcard(s) are supported by ALSA

Look for your soundcard here: http://www.alsa-project.org/main/index.php/Matrix:Main
Success: Your soundcard is listed. Move on to Check 6
Failure: Your soundcard isn’t listed. Move on to Check 5

Check 5: Check if your soundcard(s) are supported by OSS 4
NOTICE: This technique is listed in https://help.ubuntu.com/community/SoundTroubleshooting as a last resort. Use this technique with caution because it removes ALSA, the default sound system in Ubuntu. Do not be surprised if you sometimes randomly log out.

Look for your soundcard here: http://opensound.hg.sourceforge.net/hgweb/opensound/opensound/file/3db750724c2d/devlists/Linux
Success: Your soundcard is listed. Follow the instructions here: https://help.ubuntu.com/community/OpenSound, and then here: http://ubuntuforums.org/showpost.php?p=9872284&postcount=4
Failure: *TODO: Add more info*

Check 6: Check if your the driver for your soundcard(s) is installed

Type in the terminal window:

sudo modprobe snd-

DO NOT PRESS ENTER. Press the TAB key twice.
Press y if it asks you if you want to see all results
Look for your soundcard driver. Mine is via82xx, so I found: snd-via82xx.
Success: You found your soundcard driver. Type in the rest of your soundcard driver, and press ENTER.
Type in the Terminal window:

echo "snd-yoursoundcarddriver" | sudo tee -a /etc/modules

Reboot, then open up a Terminal window, and type in it:

aplay -l

Success: You should see your soundcards. Follow the alsamixer section
Failure: *TODO: Add more info*

Failure: You didn’t find your soundcard driver.
Type in the Terminal window:

sudo apt-add-repository ppa:lkjoel/apt-undo
sudo apt-get update
sudo apt-get install apt-undo
apt-undo purge linux-sound-base alsa-base alsa-utils
apt-undo undo

Reboot, then open up a Terminal window, and type in it:

aplay -l

Success: You see your soundcards. Follow the alsamixer section
Failure: You didn’t see your soundcards.
Follow these instructions: http://ubuntuforums.org/showthread.php?t=1681577

Using Alsamixer

Type in the Terminal window:

alsamixer

Success: You should see a nice mixer
To navigate, use the left and right arrow keys
To increase/decrease volume, use the up and down arrow keys, respectively
To mute/unmute, use the M key. Unmuted channels should appear green at the bottom.
To exit, use the Esc key.

To store your settings for the next boot, exit, and type in it:

sudo alsactl store 0

Or if this is your nth sound card (where n is the number of soundcards in your computer) replace 0 with n-1 (so if this is your second sound card, replace 0 by 1).

To test your sound, exit, and type in it (you might have to repeat it a few times):

aplay /usr/share/sounds/alsa/Front_Center.wav

Success: You hear sound
Failure: You do not hear sound.
Follow Check 2

Failure: Follow Check 2

    I don’t know if its Debian Sid with its alsa and kernels, or KDE 4.X in Debian Sid, but it seems that every update brings me KDE Phonon messages of ‘Your sound setup has changed’ and very often, non-working audio. A simple restart of Alsa sometimes fixes this, other times I have to re-order my Phonon devices, and other times I have to reboot (even after a fresh boot) and it works again.

    Frustrating.

    Seems like PulseAudio is troublesome for alot of people! I wrote a li’l tutorial for removing it in Xubuntu 10.04, but I’ll link to your much more in-depth post! Thanks!

    I now have sound but not able to save the setting of alsamixer by using this command “sudo alsactl store 0″ every time I shut down then next time I reboot there is no sound, so I have to open a terminal and go through the alsamixer and unmute the master m.

    • lkjoel October 20, 2011 at 6:07 pm

      Could you give me the output of this command?
      aplay -l; echo "SUDO"; sudo aplay -l

      Which device of the 2 do you use for sound (Intel ICH or Intel ICH – IEC958)?

  7. Michael Muscat October 21, 2011 at 10:06 pm

    I do not know, I thought they are the one card. How do I find out?

    On using this command lspci -nn | grep ’04[80][13]‘
    I get this result
    carolm@carolm-OptiPlex-GX620:~$ lspci -nn | grep ’04[80][13]‘

      What ubuntu release do you have?

  8. Michael Muscat October 21, 2011 at 10:38 pm

    I have Ubuntu 11.04

    When I use the following command to save the alsamixer I get the following.

    carolm@carolm-OptiPlex-GX620:~$ sudo alsactl store 0
    [sudo] password for carolm:
    Home directory /home/carolm not ours.
    carolm@carolm-OptiPlex-GX620:~$

    • lkjoel October 21, 2011 at 10:45 pm

      Weird, I’ve never had that problem.
      Could you give me the full output of this Terminal command?
      sudo alsactl store 0 || echo $?

      I hope it will give a number at the end.

  9. Michael Muscat October 21, 2011 at 11:10 pm

    carolm@carolm-OptiPlex-GX620:~$ sudo alsactl store 0 || echo $?
    [sudo] password for carolm:
    Home directory /home/carolm not ours.

    When I open the home folder there is a file named alsa-info.sh
    in properties it says type: shell script (application/x-shellscript)

    • lkjoel October 21, 2011 at 11:15 pm

      Cool! Please run it by this command:
      bash ~/alsa-info.sh
      Select the option to upload the file, and give me the link here. Then I can closely examine the problem.

    • lkjoel October 21, 2011 at 11:24 pm

      Seems good, except for the old driver version.
      Could you run the command after a reboot (i.e. after the alsamixer settings were reset)?

  11. Michael Muscat October 21, 2011 at 11:30 pm

    I ran the command after the Alsamixer was reset.
    Should I run the command after I reboot and before the reset of the alsamixer.
    remember after I reset the alsamixer the sound works OK it’s just that it will not save the reset.

    • lkjoel October 21, 2011 at 11:32 pm

      Before the reset, and give the URL generated here.

    • lkjoel October 23, 2011 at 4:33 pm

      OK, when you have changed your settings, check out this link: http://alsa.opensrc.org/Using_alsactl_to_preserve_volume_state

  13. Peter March 1, 2012 at 9:59 am

    This doesn’t help me. My alsa works fine… it is new experimental untested junk like pulseaudio and gstreamer used by KDE4 that are the problem.

    Running this seemed to fix it for a minute, and then it was broken again automatically:

    sudo apt-get install –reinstall gstreamer0.10-alsa gstreamer0.10-plugins-base gstreamer0.10-plugins-good gstreamer0.10-pulseaudio qtgstreamer-plugins pulseaudio pulseaudio-esound-compat pulseaudio-module-x11

    Why are there so many people that have reinvented the wheel so now we have a huge number of sound servers and interfaces which all fail the same way at the most basic tasks (possibly simply because multiple are installed at the same time and are fighting)?

    • Peter March 1, 2012 at 10:02 am

      And BTW the only thing that shows up in the KDE sound settings is PulseAudio. If ALSA showed up, I would simply choose that and everything would be fine. Can I just uninstall PulseAudio? Highly detailed help like the above is great, but doesn’t apply to this Ubuntu packaging problem, so I don’t know what to try.

      • lkjoel March 8, 2012 at 11:28 pm

        You might want to try my new guide (much more detailed, and has more steps) at: https://docs.google.com/document/d/1iTlJ8BfqXUjaHO__TEdlkvuqB1WLOkGaudngc5SFLMI/edit
