Bug Description
Binary package hint: pulseaudio
alsamixer shows my sound card (Intel Corporation 82801H (ICH8 Family) HD Audio Controller) has these microphones:
* mic
* front mic
* digital
Pulseaudio's volume control, however, only shows 'Microphone 1' and 'Microphone 2' for the available input ports and neither of these capture sound. gnome-volume-
However, digital mic is the built-in mic so I need to use it for audio recording applications.
A workaround is to select the digital microphone from alsamixer (pulseaudio still shows microphone 1).
However, I expect pulseaudio to show the digital mic if alsa can see it.

The only solution to make microphone work is to install linux-backports
Just go to:
Menu / System / Administration / Synaptic Package Manager
And search and mark for installation:
linux-backports
tip: if you have multiple versions click on the first and read the description which should inform what name to install...
If after the reboot and mic mute is off, still does not work, just go to terminal and type:
sudo nano /etc/modprobe.
and add or change the following:
options snd-hda-intel model=auto enable=yes
Then Ctrl+X, type Y to write and exit, reboot and mic will work.
Bye and have lots of fun with Ubuntu (the best).
