Public bug reported:
internal mic on the dell vostro a90 doesn't work with the stock karmic
install.
audio output doesn't work by default either, but i was able to fix that
by adding "options snd-hda-intel model=dell" to /etc/modprobe.d/alsa-
base.conf.
but nothing for the mic.
see the attached files for details.
