Thread: lost snd-mix after kernel update

  1. #1

    Default lost snd-mix after kernel update

    I have Opensuse 10.3 and after update of kernel on 2.6.22 I lost my snd-mix. I can hear sound but without volume control. It si by default on middle volume.
    snd-mix is not listed in output of lsmod command.

    Thanks,

    Do you mean snd-mixer-oss? When I search for all snd occurences on my openSUSE-10.3:
    rpm -qa --filesbypkg | grep snd
    I noted only the snd-mixer-oss.ko and snd-mixart.ko sound modules:
    Code:
    /lib/modules/2.6.22.18-0.2-default/kernel/sound/core/oss/snd-mixer-oss.ko
    /lib/modules/2.6.22.18-0.2-default/kernel/sound/pci/mixart/snd-mixart.ko
    I find no such "snd-mix" module.

    Did you perhaps change your alsa modules after a kernel update? To investigate that possibility, how about checking if any recent updates to your kernel resulted in a downgrade of your alsa? I think < not sure > that if a replacement alsa was installed, it will show up if you type:
    rpm -qa --last | grep alsa

    ... also, for completeness, on my openSUSE-10.3 PC, when I type "lsmod |grep snd" I get:
    Code:

    Hello,
    I put "snd-mix" module because I was reported by alsamixergui that snd-mix cannot be loaded.
    Actually, when I do : lsmod
    there is no snd-mix-oss module and loudspeaker icon does not appear on the right side of taskbar on my desktop. I hear sound but with default values.
    I cannot sart alsamixer in terminal too.

    I did not configure anything on alsa, update of kernel was done automatically and I di dnot interfere in anything; just noticed that mixer is missing and that sound volume is not possible to increase.

    When I type lsmod |grep snd I get:
    snd_seq 66740 0
    snd_seq_device 24460 1 snd_seq
    snd_hda_intel 285596 1
    snd_pcm 94852 1 snd_hda_intel
    snd_timer 39044 2 snd_seq,snd_pcm
    snd 70452 7 snd_seq,snd_seq_device,snd_hda_intel,snd_pcm,snd_timer
    soundcore 23748 1 snd
    snd_page_alloc 26760 2 snd_hda_intel,snd_pcm

    please advise.

    Best wishes,

    veki

    You do not have to "configure anything". It CAN "just happen" dependent on what version of alsa you had in place before the kernel update, and dependent on what dependencies that alsa version had with the existing kernel.

    Seeing what kernel modules you have loaded is helpful, but I need more. I need the alsa application/driver information I asked. ie specifically:

    No worries (from my point of view) if you can't do that. Without that data, maybe someone else will chime in and help you.

    Good luck in your efforts.

    I think
    (1) you have the wrong versions of many of your apps, and
    (2) you may have too many applications ... or your update to the latest alsa was not done properly.
    You have updated to alsa-driver-kmp-default to a 1.0.16 version, ... but have not updated the remainder, but left them at 1.0.14 or 1.0.15. Why? Don't you think that is opening your self up to possible version incompatibility problems.

    Also, why so many alsa apps? for example, on my 11.0 pc my mixer (kmix) works well ...
    Code:
    oldcpu@stonehenge2:~> rpm -qa | grep alsa
    alsa-utils-1.0.16-35.1
    alsa-1.0.16-39.1
    alsa-devel-1.0.16-39.1
    alsa-plugins-1.0.16-57.1
    alsa-oss-1.0.15-48.1
    and on my 10.3 PC my alsa works well:
    Code:
    oldcpu@stonehenge1:~> rpm -qa | grep alsa
    alsa-utils-1.0.14-27
    alsa-1.0.14-31.2
    alsa-plugins-1.0.14-41
    alsa-devel-1.0.14-31.2
    alsa-oss-1.0.14-23
    You can see I only have a fraction of the apps you have.

    No. You added them manually. You will have to clean them up manually.

    Hello,
    I replaced all alsa packages and install again. When I run alsaconf it is setup correctly and I was prompted that alsa is ready and volumes adjusted...
    but I do not have sound again.

    I gues that something else is probelm and that obviously system integration may be issue with big smp kernel for opensuse 10.3.

    Best wishes,

    Vedran

    I thought you could hear sound, but "without volume/mixer control"? Now you have no sound at all?

    Please can you type the following in an xterm/konsole and post here the output, so I can see what you installed:
    rpm -qa | grep alsa
    rpm -qa | libasound2
    cat /etc/modprobe.d/sound


    and also run these two scripts, and post here the output URL that they will provide you:
    Code:
    wget -O alsa-info.sh http://www.alsa-project.org/alsa-info.sh && bash alsa-info.sh
    and for the following script enter your root password when prompted and type "NO" if you do not understand the question.
    Code:
    su -c 'wget -O tsalsa wget http://home.cfl.rr.com/infofiles/tsalsa && bash tsalsa'
    Don't forget to post the URLs they provide here.
