Public bug reported: I am running Natty (11.04) doing multiple updates daily.
The internal mic in my Lenovo Thinkpad 13" (Intel) did not work until I added the "thinkpad" option to snd-hda-intel like this: ----%<---- /etc/modprobe.d/alsa-base.conf:options snd-hda-intel model=thinkpad ----%<---- As of yesterday, (2011-03-24) my mic is silent again. Skype, empathy video chat all worked, but now that's over..
