Public bug reported: I have a thinkpad edge 11" (intel) which uses the Conexant CX20582 (Pebble) sound chip.
Currently, the internal microphone will not work. Out of the box, the headphones and external mic also have issues but these get solved following directions in https://bugs.launchpad.net/ubuntu/+source/linux/+bug/587388 Following the solution listed in this bug report and setting my /etc/modprobe.d/alsa-base.conf to options snd-hda-intel model="olpc-xo- 1_5" the headphone and external microphone seem to work, but the internal microphone seem not to work. The options in alsa-mixer seem not to match the physical hardware layout. My guess is that the configuration of the pebble chip in the laptop is not supported by the drivers yet. Let me know how else I can help.
