Title:
Inbuilt microphone not working on Thinkpad Edge 13 0196CTO
Status in alsa-driver package in Ubuntu:
Incomplete
Bug description:
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.
