Ubuntu – Internal microphone not listed in sound settings

12.04alsamicrophonesound

On a fresh 12.04 installation in sound settings the internal microphone is not listed (worked upto 11.10).
Alsamixer shows that mic is "0" and muted, but after changing that it remains undetected in sound settings.

Any help? Could also be a bug (https://bugs.launchpad.net/ubuntu/+source/alsa-driver/+bug/990211).

Best Answer

My microphone stopped working when I upgraded to 12.04 LTS.

  • I installed Pulse Audio Volume Control. One way to do this is:

    sudo apt-get update
sudo apt-get install pavucontrol

    Then:

  • Under the "Configuration" tab, selected "Analog Stereo Duplex".

  • Under the "Input Device" tab, pushed the mute button (which unmutes if muted).

Now my microphone works.
