Public bug reported: Per https://wiki.ubuntu.com/DebuggingSoundProblems, reporting that the builtin/onboard microphone does not work "out of the box" on a Thinkpad Edge 13 0196CTO. An external mic plugged in to the "combo" headphone/mic jack does work. Builtin speakers and also headphones work fine, and switch back and forth when the mic/phones are plugged in.
>From http://ubuntuforums.org/showthread.php?t=1609411, I tried using 'options snd-hda-intel model=laptop' in /etc/modprobe.d/alsa-base.conf, which after rebooting enabled the internal microphone, however disabled the switching between the internal mic+speakers and the external jack (i.e. plugging in the external mic/phones had no effect, audio in & out was still from the builtin devices). I don't see any option in /usr/share/doc/alsa-base/driver/HD-Audio-Models.txt.gz that matches this hardware. Output from ubuntu-bug audio attached.
