Sound not working (module loaded but device node is missing)
  • pfichtnerpfichtner January 2010
    Hi,
    unfortunately I can't get the sound working on my slitaz cooking. The kernel module is loaded without complains but amixer, alsactl and alsaconf can't find a soundcard

    hello Peter,

    This post may help:

  • pfichtnerpfichtner January 2010
    Hi Cavalier,

    thanks for your hint! I'll try it by installing the mentioned package.


    Peter
  • pfichtnerpfichtner January 2010
    Unfortunately none of the both packages did solve my problem.

    If I am right the solution fixes a problem with unresolvable symbols, my problem is that the kernel module loads without errors or warnings but alsaconf, amixer, etc. cannot find a soundcard.
  • asimoasimo January 2010
    I had a similar problem recently. Sound modules loaded, but no sound on cooking based SliTaz.
    I solved by installed the package:

    tazpkg get-install util-linux-ng-getopt --forced


    hope this help

  • pfichtnerpfichtner January 2010
    Hi Asimo,

    the package is already installed:

    tazpkg list | grep getopt

    util-linux-ng-getopt 2.16.1 base-system

    I reinstalled util-linux-ng-getopt and alsa-utils (which depends on util-linux-ng-getopt) but nothing changed :-(

    Anyway: Thanks for your help

    Peter

    but amixer and alsactl still complain

    root@slitaz:~# amixer

    amixer: Mixer attach default error: No such file or directory

    root@slitaz:~# alsactl init

    alsactl: init:1727: No soundcards found...




    Is this an ALSA related bug?




    Thanks!

    Hi,

    It maybe an udev bug, device are not corectly created. After boot does /dev/snd exist and is it populate ? If not, please try as root:

    # udevadm trigger


    - Christophe
  • pfichtnerpfichtner January 2010
    Thanks for your comment, Christophe!

    I forget to mention that I already did trigger udevadm, sorry!

    Should I add an issue at http://labs.slitaz.org/issues? How can I do this?

    Thanks Peter
  • skralljtskralljt January 2010
