    Re: Sound and Mic Problems on EeePC 1018p

    no luck. I can't tell any difference. The right and left mic input channels are still "locked" (i.e. the shield button is depressed) every time I restart pavucontrol, but the right input channel will stay at 0, and the left at 100.

    Any other ideas? Again, thanks for looking into this.

    Open alsamixer, press <F4> and take a screenshot. Then post here if you would please.

    I have the exact same issue on the exact same netbook. Anyone have any ideas on this? It works on ubuntu 9.10 but not on 10.04.

    Code:
    Getting Line Input to work (Microphone, etc)
    
    Changing default subdevice configuration
    
        * Some sound devices have multiple capture subdevices (eg. hda-intel), but pulseaudio only seems to detect the parent device, and only listens to subdevice #0. ALSA may not be configured to use your preferred device as subdevice #0 by default.
              o
    
                Open the pulseaudio record meter (pavumeter --record)
              o Talk into your chosen device while you carry out the process and watch the meter.
                    + Some channels are quite noisy even with no input (especially on integrated chipsets), so we are watching for movements that correspond to our voice. 
              o
    
                Use alsamixer -c n (where n is your sound card number, probably 0)
                    + Press F4 to get to the capture console
                    + Make sure the first capture channel is enabled ("CAPTUR" in red, press space to toggle), and the volume turned up.
                    + Check the first input source is switched to your chosen plug (Mic, in my case) 
              o At this point, you should see the record meter bouncing in response to your voice.
              o I found that I had to repeat this procedure each time I wanted to use the Mic, even though the settings "stuck" in the mixer, something in the soundcard wasn't initialized until it was repeated.
              o This also works if you use the "Options" tab in the standard mixer app to do the same thing.

    Still the same old story. I've used a USB mic successfully, so it's not the high level software that's an issue. Funny. I see a very regular ~1 Hz pulse in the mic channel--both actually (it's still stereo).

    There must be something I'm not seeing - probably something basic.
    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
    Enter your user password when prompted. Choose the upload option and provide a link for the output.

    Try upgrading your alsa install. Use the link in my sig. But first remove any custom entries from alsa-base.conf
