Please check to see if your mic is inverted "Install the pavucontrol application, start it and go to the "Input Devices" tab. Unlock the channels (there is a keylock icon), then mute the right channel while keeping the left channel at the volume you want. If the internal mic is now working correctly, you have an inverted internal mic, so that your right channel cancels out the left one." -- https://bugs.launchpad.net/ubuntu/+source/alsa-driver/+bug/1002978
