Solved with a clean install!

[Launchpad Janitor (janitor)]

Status changed to 'Confirmed' because the bug affects multiple users.

[Pierre (pierrewinnipeg)]

I found a solution:

1) I installed gnome-alsamixer

2) Under the 2 Capture options, I turned "rec." on.
I have no idea what this means (record?), but it solved the problem.

Alsamixer (commandline ) DOES NOT HAVE such an option. Alsamixer needs to be fixed.

This should be considered a major problem, microphones nowadays are essential and many people will dump Ubuntu if it cannot work.

Same issue for me with also a Realtek ALC883. The microphone doesn't work anymore after upgrade to 12.04
The 2 capture options were already turn on so #4 doesn't help for me and not so keen on redoing a fresh install ...

Simple mixer control 'Channel Mode',0
  Capabilities: enum

it is bug of driver , after the rear mic jack and line in retasked as output. rear mic jack and line in jack kcontrol should always return false

[Raymond (superquad-vortex2)]

when driver change the pin ctl of rear mic jack or line in jack from IN to OUTit should also change the value of jack detect kcontrol to false
