    Microphone not recording

    Hi all,

    Problem:
    I can hear myself speak in the mic but Ubuntu is not recording/capturing the sound.

    Actions Taken:
    I followed all the steps listed here for the Alsa update script

    I've also tried changing my /etc/modprobe.d/alsa-base.config file with the following configurations one at a time.

    Code:
    options snd-hda-intel model=auto
    options snd-hda-intel model=acer
    options snd-hda-intel model=3stack
    options snd-hda-intel model=generic
    I am at a loss of what to do. Thanks for your time.

    Other info:

    Im running Ubuntu Natty Narwahl dual booted with Win7 on a Acer Aspire 5542G laptop.

    Code:
    cat /proc/asound/card0/codec#* | grep Codec
    
    Codec: Realtek ALC888
    Codec: Conexant ID 2c06
    Code:
    aplay -l

    My capture settings are 'on' in alsamixer as in they are in red with the words CAPTURE underneath it.

    Hey
    It sounds like the microphone is just working fine, but if you want to be recording yourself are you using a program/utility to do so?

    It's actually alsa-base.conf although I think alsa, at least for now, reads everything in that directory.
    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.

    You should try tweaking the values in red above.
    Try gnome-alsamixer.
    Gnome-alsamixer
    Using Alt+F2 run dialog
    Code:
     gnome-alsamixer
    Use 'Edit -> Sound Card Properties' menu to enable elements.
    Soundcard tab to select / adjust levels.
    To install:
    Code:
    sudo apt-get install gnome-alsamixer
    Then use pulseaudio volume control (pavucontrol) to select your mic in 'Input Devices' tab.

    There are 3 devices to choose from on the 'Input Devices' tab.
    Analog Microphone, Analog Line-in and Internal Microphone. I tried each one to no avail.

    I've maxed out all the volume settings for gnome-alsa mixer as well.

    Still doesn't work I'm afraid.
