    Background / Notes / Warnings
    • I can't guarantee if these instructions will work for everybody, and this is definitely a work in progress. But if these instructions can at least help one person out, I'll be happy.
    • If anyone has any suggestions or tips in making this post better, feel free to PM me or post below. Credits will be given regardless of how small the improvement.
    • If you find that you have followed the instructions on this post that something did not and you don't know why, it will be better if you start a new post and cite the fact that you used the instructions on this guide to solve your problem. Your post might get lost in all the other posts and you might not get help.
    • If you however find a solution to your problem, and you fee that the solution should be here, don't hesistate to post. However, please be specific.
    • If you cannot use hear anything, and you have just installed Ubuntu, then it could very possibly be a bug. It could be something as simple as not detecting your hardware the first time or evidence of a deeper problem. As fun as it is to find workarounds and fixes on your own or with help, Ubuntu developers need your feedback to see what is not working for you. That's right ladies and gentlemen, they would really really like it if you would file bug reports on http://launchpad.net under the Ubuntu distribution.
    • Note: To make it absolutely clear, when I say 'Ubuntu', I mean Ubuntu AND Kubuntu AND Xubuntu (for people who find this confusing - just accept it and don't feel bad - I and probably a whole lot others got confused when we started out).
    • Important syntax note: ALSA modules are denoted by the prefix 'snd' followed by the dash ' - ', followed by the module name (i.e. 'via82xx'). So the full name might be something like snd-via82xx. However, in some cases you will see an underscore ' _ ' instead of the dash. This is OK, do not let it confuse you. For all intensive purposes (installing modules or posting on forums) only use the dash ' - '.
    General Help - Start here if you have no idea why sound is not playing

    (1) Go to a shell and type:
    Code:
    aplay -l
    • Success - You will get a list of the all the soundcards installed on your system. Your sound just might be muted. See alsamixer section.
    • Failure - You will get a message like
      Code:
      aplay: device_list:221: no soundcard found...
      Move on to step 2.
    (2) Type this into the shell:
    Code:
    lspci -v
    • Success - At this point, you should see your sound card listed. This is a positive sign because it means that Ubuntu is detecting the presence of your soundcard, but the drivers are not installed/running. Leave your shell running since you will need it.
    • Failure - If it is not listed, then there are a few things that you can do.
      • If your soundcard is an onboard sound card, then it might be disabled in the system's BIOS. You will have to reboot and hit the key that lets you enter into the BIOS (usually Delete, F2, or F8).
      • If your soundcard is not onboard, make sure that it is properly seated in the PCI slot. If your card is working under Windows then this is not a problem.
    (3) Check to see if the ALSA driver for your sound card exists. Go to http://www.alsa-project.org/alsa-doc/ and search for your sound card (chipset) manufacturer in the dropdown box. You'll be given a matrix of the sound cards made by the manufacturer. Try to match the chipset you found in step 2 with the driver(green hyperlink text).
    • Success - You will have found the driver for your soundcard's chipset.
    • Failure - You will have not found the driver for your soundcard chipset. (at the moment I cannot help you, but stay tuned!)
    (4) Now go back to the shell and type
    Code:
    sudo modprobe snd-
    Now, press the TAB key BEFORE pressing the ENTER key to see a list of modules. Try to find the module that matches the driver you found in step 3.


    For example, my driver is a via82xx so I would type, sudo modprobe snd-via82xx.
    • Success
      • A success here means that your soundcard was installed, but it was not being loaded. Now you have loaded it for the current session.
      • To load it for all sessions (you will probably want to do this) you will have to edit /etc/modules (I think this is the file, I'll check once I get to my Dapper PC).
      • Type this into the shell
        Code:
         sudo nano /etc/modules
      • Add only the name of the module to be loaded at the end of the file. In my case, the via82xx module gave me sound so I added "snd-via82xx" to the end of the file.(iii) Make sure that you have all channels unmuted in alsamixer
      • See the alsamixer section
      • Play media using your favorite media player. Set your audio engine to alsa. In some cases, you have to configure your audio engine within another (media engine) like in Kaffiene in Kubuntu. If you hear sound, hurray!
      • One final step. Go onto Saving Sound Settings
    • Failure -You have two options
    • Move on to Getting the ALSA drivers from a *fresh* kernel. This step is easier and is recommended to users who might have been tinkering with their sound settings and want to revert back to the way it was just after installing Ubuntu (without reinstalling Ubuntu of course )
    • Move on to ALSA driver Compilation, if you have not done so already. If you have, please post a new thread with your problem.

    Getting the ALSA drivers from a *fresh* kernel


    Sometimes, sound might be configured correctly, but for some reason or another (tinkering) it stops working. One way to go back to the old setup is to reinstall Ubuntu. However, this step is actually quite unnecessary since you are reinstalling everything because of one thing.


    A faster way, is to just remove the problematic packages and reinstall them cleanly.


    (1) Remove these packages
    Code:
    sudo apt-get --purge remove linux-sound-base alsa-base alsa-utils

    (2) Reinstall those same packages

    Code:
    sudo apt-get install linux-sound-base alsa-base alsa-utils

    [LIST][*]
    VERY IMPORTANT NOTE: Ubuntu (GNOME) users have reported that packages 'gdm' and 'ubuntu-desktop' are removed after removing the linux-sound-base packages. If this happens, then do the following
    Code:
    sudo apt-get install gdm ubuntu-desktop

    (3) Reboot
    [*][LEFT]
    VERY IMPORTANT NOTE: Xubuntu (XFCE) users have reported that packages 'gdm' and 'xubuntu-desktop' are removed after removing the linux-sound-base packages. If this happens, then do the following
    Code:
    sudo apt-get install gdm xubuntu-desktop

    (3) Reboot
    Now you may ask "I already had the packages, so why did I go through the trouble of removing them, then installing them". The answer lies in the --purge option which removes all the extra information that accumulated from tinkering and upgrading. After doing a purge then install, the packages are unpackaged as if it they are brand new.
    (4) At this point, try using
    Code:
     aplay -l
    you should get your soundcard listed.
    • Success - Your soundcard is detected. Go onto the Using alsamixer section, then try playing something on your music or media player.
    • Failure - Your card was not detected. You should try compiling your driver, so go onto ALSA drive Compilation.
    ALSA driver Compilation
    • If you are here, then either your soundcard driver could not be loaded with modprobe, or you want to compile the drivers yourself from scratch. Good luck to you!
    • There are two main ways the sources of alsa-drivers are made available to you. One is though the apt-get system. Using this system would be the recommended system since most of the heavy lifting is done for you.
    • The other way, is getting the latest drivers from alsa-project.org. This page has the latest drivers available, which you might want to fix problems with. However, these have not been tested with Ubuntu and therefore should be used with caution.
    Using alsa-source
    1. Type the following to shell: (note: module-assistant is optional, it will compile the package for you)
      Code:
      sudo apt-get install build-essential linux-headers-$(uname -r) module-assistant alsa-source
    2. Code:
      sudo dpkg-reconfigure alsa-source
    3. You now have a big blue dialog box (left and right keys to choose 'Yes' and 'No', Enter key proceed). Answer yes (for ISA-PNP - recommended by package maintainers), then yes again (for debugging - recommended by package maintainers).
    4. Now you must pick which driver you want to install. Use space to select and deselect modules, and up and down to navigate.
    5. From General Help step 3, you should know the name of your driver. Deselect 'all' (the * will go away), and select your driver. In my case, I deselected 'all' then selected 'via82xx'. Hit Enter. Almost home free!
      • If you chose module-assistant
        Code:
        sudo module-assistant a-i   alsa-source
        If the progress bar reaches 100% with no errors, you will have installed the drivers successfully. Resume this guide from General Help step 4.
      • If you did not choose module-assistant - Remember the name of your soundcard driver and use it place of the blue text below.

        Code:
         cd /usr/src sudo tar xjvf alsa-driver.tar.bz2 cd modules/alsa-driver
        Code:
        sudo ./configure  --with-kernel=/usr/src/linux-headers-$(uname -r) --with-cards=<enter driver name here e.g. via82xx> --with-oss=yes 
        sudo make  
        sudo make install
      • Code:
        
        


    If you get no error messages, you will have installed the drivers successfully.
    • Success - Resume this guide from General Help step 4.
    • Failure - Start a new thread in this thread of the forum. Paste the error message that you get and state that you were following instructions on this page.
    Using drivers from alsa-project - update I now recommend using the stable version 1.0.12
    • The alsa-project route is very similar to the alsa-source route without the module-assistant.
    • First you would have to get the alsa-driver tar from alsa-project then pretty much do configure, make and make install again.
    • However, I do recommend that you make a specific directory when you compile something from source. Remember the name of your soundcard driver and use it place of the blue text below.
    Code:
     
    
    mkdir src cd src
    mkdir alsa
    cd alsa
    sudo apt-get install build-essential linux-headers-$(uname -r)
    wget ftp://ftp.alsa-project.org/pub/drive....12rc2.tar.bz2
    tar xvjf alsa-driver-1.0.12rc2.tar.bz2 cd alsa-driver-1.0.12rc1 sudo ./configure --with-kernel=/usr/src/linux-headers-$(uname -r) --with-cards=<enter driver name here e.g. via82xx> --with-oss=yes sudo make sudo make install
    If you get no errors from doing the above then you have successfully compiled alsa-drivers from source. Resume this guide from General Help step 4.


    Using alsamixer
    • Type this into a shell
      Code:
      alsamixer
    You will now see what appears to be a graphical equalizer. It is more like ten different volume controls in the sample place.
    • To navigate around:
      • Left and Right Arrow Keys - Move left and right (if you move long enough in one direction you will get back to where you started - you will not fall off the screen )
      • Up and Down Arrow Keys - Increase and decrease volume respectively.
      • Letter M Key - Mutes/unmutes. If a channel is unmuted, then there is a green box underneath the volume slider. If the channel is muted, the box is grey.
    Saving Sound Settings
    Do this step to ensure that your alsamixer settings are reloaded with each boot. First make sure you have your settings just the way you like them in alsamixer. Then do
    Code:
    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. Many thanks to xpix for trying this out.-


    Getting more than one application to use the soundcard at the same time
    • You might want to play a game and listen to music on your favorite music player at the same time. To do this successfully, you will have to use ALSA since it supports this feature the best. On all the music players I know of, you can configure the sound engine, to any module that is available.
    • The setting is usually found under something like Tools >>> Configure >>> Player Engines.
    • For games, it is a bit more tricky since there is not always a way to configure the player engine directly. Most games, however, do support the OSS. ALSA has an OSS module that allows OSS applications to use the ALSA driver.
    • To do this you will need the alsa-oss package
      Code:
      sudo apt-get install alsa-oss
    • After doing this step, it is very easy to use alsa-oss. In the shell, you can type 'aoss' then the name of the program name you want to use with alsa-oss.
    Configuring default soundcards / stopping multiple soundcards from switching

    Note: This section assumes that you have installed each soundcard properly.
    • In a shell, type
      Code:
      cat /proc/asound/modules
    • This will give the the name and index of each soundcard you have currently. Make a note of the names, and decide which one you want to be the default card.
    • Now type
      Code:
      sudo nano /etc/modprobe.d/alsa-base
    • At the very end of the file, add the following (assuming you have 3 cards with module names A, B and C and you want to have them in the order CAB)
    Code:
    options snd-C index=0
    options snd-A index=1 options snd-B index=2
    Adding the current user to the audio group


    A very common cause for a user to not have sound is not having his/her username in the /etc/group.

    Thanks to rustybutt for this simple check.

    Code:
    grep 'audio' /etc/group
    You should see a line similar to
    Code:
    audio:x:29:
    followed by a username i.e. if the username is "ubuntu" then you should see
    Code:
    audio:x:29:ubuntu
    . If you see something else i.e.
    Code:
    audio:x:29:root
    you should add your username to the file by doing
    Code:
     sudo nano /etc/group
    . Now find the line that looks like
    Code:
    audio:x:29:root
    and change it to
    Code:
    audio:x:29:root:moocow
    only replacing moocow with your real username.

    Hit CTRL + 0 to save, then CTRL + X to exit. That's the end of that



    Getting MIDI To Work - *EXPERIMENTAL*

    This section assumes you can successfully hear sound from your soundcard.
    First of all, make sure that you actually have a MIDI port on your soundcard. Most onboard soundcards do not have a MIDI port.

    Next, open up this file:

    Code:
    sudo nano /etc/modprobe.d/alsa-base

    Then add this options line

    Code:
     options <snd module name here i.e. snd-via82xx> mpu_port=0x330

    OR if you already have a options line for this soundcard add
    Code:
    mpu_port=0x330
    to the line.

    The default MIDI port is 330. You should verify this number in your BIOS if you are not sure. If the number is not listed, it is most likely that the number is 330 (add the 0x for the file).

    If you get no errors, you have successfully installed your MIDI port. At the moment, I do not know if any further configuration is necessary.

    Miscellaneous Tips and Tricks

    Here are a few things that other people have dug up over the course of this guide. Not all tips are meant to work for all hardware (believe me hda-intel will probably have like a mini guide of it's own one day).
    I wasn't getting any sound out of my Sony Vaio PCG-4B1L ...
    The crucial thing is to enable everything in alsamixer EXCEPT "external amplifier." (I had to turn off microphone too, to stop feedback).
    • Useff had a very annoying problem where he could get sound through alsa from one user, but not through is main account. http://www.ubuntuforums.org/showthread.php?p=1221754. Him and I managed to fix the problem by making sure the main account was in the audio group in /etc/groups (which he was) and deleting the .asoundrc file in the main account's /home directory.
    • Bo Rosén solved his ISA problem the following way. Thanks to FarEast for his help in the matter.
      Thanks to http://ubuntuforums.org/showthread.php?t=127402 this post I got soundblaster 16 isa working. In short add
      Code:
      snd-sb16
      to /etc/modules then create a new file:
      Code:
      gedit /etc/modprobe.d/sound
      and enter this line:
      Code:
      options snd-sb16 isapnp=0 port=0x220 irq=5 dma8=1 dma16=5
      Code:
      sudo update-modules
      reboot
    • webbca01 figured out how to get AC'97 work with the help of the second last post here and this post. Basically, if you have an intel8x0 module, you can get AC'97 working by
      Code:
      sudo nano /etc/modprobe.d/alsa-base
      and adding this as the last line:
      Code:
      "options snd-intel8x0 ac97_quirk=3"

    To Do:

    Important - no particular order
    • Getting MIDI to work
    • Compiling alsa entirely (drivers, utils, oss, etc)
    • Getting line input to work if it does not already - for microphones, etc.
    • Getting SPDIF output to work if it does not already - for amplifiers, speakers with digital in.
    On the backburner
    • Scripts for getting configuration that needs to be done in this post to be done automatically

    Re: Comprehensive Sound Problem Solutions Guide

    Hi. I'm newbie to linux.since i first installed to my laptop, I've had problem with the sound. I've tried everything but nothing seems to work. Alsa installation went smoothly but no sound still. I also tried the OSS version but doesn't seem to work too. no error messages but NO SOUND. I found a file in driverguide but made for redhat. I wonder if it could be used in ubuntu?

    Re: Comprehensive Sound Problem Solutions Guide

    Well, I don't know what I did, but sound is fine now. I made so many changes according to different threads in this forum, that I got confused about what I added and deleted, so I wound up just reformatting and installing ubuntu all over again from scratch. All of the sudden....sound works!

    Now if I can just figure out how to control the volume from my keyboard, lol.

    Re: Comprehensive Sound Problem Solutions Guide

    Hi,
    I've installed Ubuntu 8.04 today (first time Linux user) and I'm not getting any sound. The guide was very helpful, I followed all the steps, and everything worked except that I still don't have any sound.
    My card is listed, and I believe I managed to install the driver?
    My card is Creative Labs SB Audigy LS, and I did the snd-ca0106 which is the driver specified.
    Any help would be much appreciated. I'm not sure what other info you need, but I'd be happy to supply it if I can. I'm very new with the terminal and commands, so I find explanations of the commands useful. Thanks

    Thanks in advance
    I first posted this enquiry under " Multi Media and Video" but now feel that this has become a General question.
    After I installed upgrades I lost my Sound with the error message " NO VOLUME CONTROL G STREAMER PLUGINS AND OR DEVICES FOUND ". It seems that there are many of us with this problem. I have tried numerous suggestions in various posts - but nothing has resolved my problem.
    I have found however that if I run UBUNTU from my installation CD - I have sound !!!!!. So can anyone tell me how I can reinstall UBUNTU from the cd or wherever WITHOUT LOSING ALL MY DATA AND PROGRAMMES, which have taken many months to get together.
    I wait in eager anticipation for any helpful suggestions.I have tried ALL suggestions made by Lord Raiden in his sticky - but nothing so far resolves my problem

    Re: Comprehensive Sound Problem Solutions Guide

    I have tried the guide and at general help (1) I was success then I did the alsa mixer thing and even tried getting alsa drivers. After that I did Alsa driver compilation the automatic one and didn't get any errors. But on general help (4) and get stuck. Sound worked on the older ubuntu. I get stuck and can't find my chipset.

    Then went to ALSA, but for the life of me, there doesn't seem to be an easy search utility on the site where I can input the above information to retrieve the right spec for the sounddriver. What must I do, no sound, and its not my computer, but an eager lass you desperately wants her machine to pump.
