    Sound and Mic Problems on EeePC 1018p

    I have an Asus EeePC 1018p and I'm having trouble debugging an audio problem in Lucid. The internal microphone does not work, nor does the headphone jack or external mic input. I've tried fiddling with alsamixer, pavucontrol (some fixes involve setting turning down the left or right capture channels), etc., but haven't had any success.

    It seems that many people with EeePCs (other models) have fixed the problems with what I mentioned above, but it's no use for me. I've also booted into UNR to see if the modified kernel that it ships with fixes any problems, but nothing changed.

    Any ideas? I don't even know which logs to look in to find the issue.

    Here is some information on my system if it helps.

    OK, well I've submitted this information to the launchpad bug found here:

    https://bugs.launchpad.net/ubuntu/+bug/601518

    Is there anything else I should do?

    asus models seem to require more fiddling than any other. It's probably workable.
    Can you post the output of these terminal commands for me please:
    Code:
    uname -a
    aplay -l
    dpkg -l | grep "alsa"
    head -n 1 /proc/asound/card*/codec#*
    Terminal="Applications->Accessories->Terminal"
    Please also include the make/model of your PC/Laptop.
    Please post text output using code tags (the # in toolbar)

    Using a Terminal="Applications->Accessories->Terminal"
    Open this file for editing:
    Code:
     gksudo gedit /etc/modprobe.d/alsa-base.conf
    Insert this line at the bottom:
    Code:
     options snd-hda-intel model=auto
    Save. Close. Reboot. Check your levels in alsamixer.
    Code:
     alsamixer
    Press <F6> to select the correct soundcard.
    Press <F3> to show playback levels. <F4> selects capture levels [or use <Tab>]
    Use the left/right arrow keys to select and up/down arrow keys to change levels. <M> to mute/unmute.
    Go to "System ->Preferences ->Sound" and make sure the correct soundcard is default and adjust your profile on the hardware tab.
