Public bug reported:
Hello,
After an upgrade to Natty from Maverick I found that the built-in
microphone stopped working, it cannot be selected via gnome-sound-
properties and it appears that there is no other input device in
alsamixer on Realtek ALC268.
I have performed a clean Natty installation recently and verified that
the mic does not on stock Natty, w/o any customizations I may have
introduced earlier.
