Kernel upgrade breaks sound

July 8th, 2009

Unfortunately, if you installed an older release and then install upgrades to a new kernel (say, from linux-image-2.6.28-11-lpia to linux-image-2.6.28-13-lpia), sound will no longer work. Release 090704 already has the 2.6.28-13 kernel, I believe.

Fix sound
If that happens, you’ll have to paste this command in the terminal:

sudo m-a a-i alsa-source

Once that’s done, reboot, and you should have sound.

Adjust user settings
You may have to change the sound settings again. These are the settings I use:

Make settings stick
Once you have the settings the way you like them paste this command into the terminal:

sudo alsactl store

    You might need to include “alsactl restore” in /etc/rc.local to get sound at boot time. This was my case

    Thanks this is great. I got it working on a HP Mini110-1000. Got sound to work on2.6.28-14-lpia by installing the linuxant alsa packages from http://www.linuxant.com/alsa-driver/archive/alsa-driver-linuxant-1.0.20.3/alsa-driver-linuxant_1.0.20.3_all.deb.zip. Remove any cruft you may have added /etc/modprobe.d/alsa-base.conf. Reboot and unmute. Also, no drivers for the ethernet card, so built from source: http://partner.atheros.com/Download.aspx?id=93:

    mkdir attansic && cd attansic
    tar xf [459]AR813X-linux-v1.0.0.9.tar.gz
    make && sudo make install
    echo “atl1e” >> /etc/modules
    modprobe -a atl1e

    Thanks again!

    Thanks Jim. This worked for me using UNR 9.04 using 2.6.28.11. I have not tried with a later version of the kernel.

    Is there anyway to unmute the input? I have tried unmuting it in the volume control and alsastore -ing it, but nothing so far has worked. Any suggestions?

    Hey, I am getting my Input settings as entirely mute, as they are above, and will consistently reset when I change them to unmute. Alsamixer doesn’t have any of them muted. Any fix for that?
