    No sound after update to 10.10

    Hi,

    I recently updated my laptop to Ubuntu 10.10 version. In the process of updating I lost all sound.

    Looking through my information I cannot see any sound card. I do have one. It's integrated on the motherboard. Worked fine under 10.04. Now not at all.

    Help?

    Try resetting your pulse configuration.
    Using a Terminal="Applications->Accessories->Terminal"
    Code:
    rm -r ~/.pulse ~/.asound* ~/.pulse-cookie 
    sudo rm /etc/asound.conf
    Logout/in.
    No joy? Use the alsa-info-script to provide detailed information.
    Run this command in a terminal:
    Code:
    wget http://www.alsa-project.org/alsa-info.sh -O alsa-info.sh && bash alsa-info.sh
    Choose the upload option and provide a link for the output.

    Thanks Lidex for the commands.

    When I ran the commands it indicated that pulseaudio is not installed.

    Please find the output below:

    Just tell me what I have to do.

    Optimally I would prefer alsa over pulseaudio. But anything is better than nothing.

    You get both with ubuntu.
    Pulse appears to be installed and running but it can only recognize hardware that alsa sees and your alsa install is borked. An alsa re-install is in order but make sure your kernel is updated first:
    Code:
    sudo apt-get update
    sudo apt-get upgrade
    sudo update-grub
    Reboot

    Code:
    sudo apt-get purge linux-sound-base alsa-base alsa-utils
    Code:
    sudo apt-get install linux-sound-base alsa-base alsa-utils gdm ubuntu-desktop
    Reboot.
    *gdm and ubuntu-desktop usually get taken out in the process, so we add them back*

    I followed all the instructions above to the letter.

    Still not getting any sound. Looking through the information, my sound card is still not being recognised.

    Please find an output below.

    Ubuntu Maverick Meerkat uses version 2.6.35 of Linux Kernel. A lot of users have solved their problems by upgrading to version 2.6.36. You can do so by downloading the deb files and installing them from the Ubuntu Kernel Mainline PPA: http://kernel.ubuntu.com/~kernel-ppa/mainline/ Open the latest version that is available (rc8 is the latest in the time of writing this, however only 64bit is available, if you have 32-bit, use rc7) and download the following files:


    linux-headers-VERSION_all.deb
    linux-headers-VERSION-generic_VERSION_amd64.deb
    linux-image-VERSION-generic_VERSION_amd64.deb


    If you have 32bit, choose the ones that contain i386 instead of amd64 in the name.
    Install them one by one in the same order as listed above and reboot.
    Note that if that does not help and if you want to switch back to 2.6.35 kernel again, you can always remove 2.6.36 kernel from Synaptic Package Manager (Alt+F2>gksu synaptic). Also note that you will not get updates to 2.6.36 even if newer versions are out, so you should update manually later if you find newer versions of 2.6.36 kernels.


    This worked for me.

    hiya, can anyone shed any light on this for me, i've suddenly lost sound recently. i have gone back to an older kernel, upgraded to the latest 2.6.37 kernel, and run the alsa script posted above, this is my output
    http://www.alsa-project.org/db/?f=76...cf3728826ceed3

    i have tested the speakers with another device, and when i boot, i get the *POP* of the driver being loaded. but when i am at the desktop, i get nothing.
    it is not muted BTW

    Ok, turns out that it was an obscure setting, only accessible in gnome-alsamixer, which had been changed somehow. i selected analog source, reverting it from digital.
    i have no idea how it got changed in the first place.
