    [SOLVED] Having issues with laptop mic detection


    Hi All,

    I am running Fedora 10 on my laptop.
    Recently I installed Empathy to use voice chat on Linux, however, Empathy does not detect the laptops inbuilt microphone!
    I have checked the audio settings and found that the mic is enabled.
    I know that the mic is working as it works fine when I am booted onto my Windows partition.

    Can anyone help me with this?

    Thanks in advance.

    Does the Mic work with any other applications? Can you determine if Empathy is the only app with this problem?

    You're certain that the mic is not muted, in your mixer settings?

    The mic works fine and I regularly use it in windows.
    As for linux, I do not have any other applications on my system other than Empathy that will require to use a mic.

    I am certain that the mic is not mute in the mixer settings as I checked all the settings before putting in this post.

    Maybe you can try Pidgin or any other App that uses a mic just to see if it works. Pidgen can probably be found in your system repos.

    I have been using Pidgin on Linux. Unfortunately it does not have the option of voice chat.

    I tried the gnome sound recorder, but its not recording anything.
    Once I press record, it hangs and the application does not exit.

    Not sure what else to try out. I have even tried with an external mic... but to no use!

    Well, I'd suggest starting from the bottom and working our way up. Please post the output of these commands as root:
    Code:
    lspci | grep -i audio
    Does your system use alsa? Pulse audio?
    Which modules are loaded?
    Code:
    lsmod
    Once I press record, it hangs and the application does not exit.
    That is not good, it's probably because of a wrong driver or something. Does your sound system work, aside from the non working mic? Have you tested that mic on another system, just to be sure.

    Hi Mike,

    First of all thanks for helping me out. Here is the outputs of that you had requested.

    Code:
    ]# lspci | grep -i audio
    00:1b.0 Audio device: Intel Corporation 82801G (ICH7 Family) High Definition Audio Controller (rev 02)
    and the lsmod output is seen below.

    I think you are right about the issue with the sound driver.
    At present I am able to use the audio outputs and connect external speakers, however, the internal speakers do not work. This used to work sometime back, but currently its not work.
    I think something major has gone wrong.
    This is not the case when the system is booted in Windows partition, where both the internal mic and the internal speakers work absolutely fine.

    If it was me, I'd ditch Fedora and try another distro....at least try some LiveCDs and see if there is still a problem. It looks to me as if the right drivers are loading. Do you see any error messages related to sound if you issue these commands?
    Code:
    dmesg | grep -i audio
    dmesg | grep -i error
    dmesg | grep -i fail
