    No sound, no /proc/asound/

    Hi,

    I have really big problem. I tried doing many many things suggested on this forum, but my sound still doesn't work. It worked before. Unfortunately I tried to make my internal mic work and well now I have no sound and no mic.

    I'm using Ubuntu 10.10. Acer 6930G. Soundcard probably hda-intel.

    aplay -l
    Code:
    aplay: device_list:235: no soundcards found...
    alsamixer
    Code:
    cannot open mixer: No such file or directory
    cd /proc/asound/
    Code:
    bash: cd: /proc/asound/: No such file or directory
    Please help! I have no clue what to do next. Also, I'm not that familiar with linux, maybe I'm missing something simple?

    Best,

    Re: No sound, no /proc/asound/

    First to try is an alsa re-install. Use this method:
    Using a Terminal="Applications->Accessories->Terminal"
    Code:
    sudo aptitude --purge reinstall linux-sound-base alsa-base alsa-utils linux-image-`uname -r` linux-ubuntu-modules-`uname -r` libasound2
    Reboot.

    Re: No sound, no /proc/asound/

    Thanks for the response!
    I did everything that you said and after reboot still no sound. System>Preferences>Sound shows no devices. I tried typing the commands from my first post - the same result.

    Any other ideas? Please help.

    PS. Here's the output from the terminal, if you want to look at it:

    Re: No sound, no /proc/asound/

    Did you reboot? 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.

    Re: No sound, no /proc/asound/

    Yes, I did reboot after reinstalling alsa, using your command.
    I tried to use the command to download and run alsa-script.sh, but because the university has proxy here, I had to download it through browser, chmod and then run it.
    Here's the output:
    Code:
    mszynisz@mszynisz-Aspire-6930G:~/Downloads$ ./alsa-info.sh

    If you do not like to proceed, press Ctrl-C now..^C
    mszynisz@mszynisz-Aspire-6930G:~/Downloads$
    I hope I did it right.
    When I choose not to press Ctrl-C, then the alsa-info.sh file is replaced by an empty file.

    Please help!

    I have changed the alsa-info.sh script so it doesn't run the update!

    Re: No sound, no /proc/asound/

    May need to re-install your kernel. Go into synaptic and mark the
    2.6.35-25-generic kernel and kernel headers for re-install, then apply and reboot.

    Unfortunately nothing has changed - on this kernel nothing works. I am now on the 2.6.35-24 kernel and everything works.
    How to make the newest kernel work? Maybe there is something that is not reinstalling during kernel re-installation?

    This fixed internal sound card issues on HP Probook 4510s and now all sound devices are listed properly (I installed with my sound card disabled in BIOS, don't remember when and why I had disabled that).
