Had the same problem as Kay A.Serenade (wind-summoner) with the external and internal mic on a Realtek ALC269 on a Asus 1015PEM using Lucid. Fixed the external mic problem by writing
options snd-hda-intel model=basic
to the end of
/etc/modprobe.d/alsa-base.conf
Don't know if it works for the headphone's jack problem though, as I never had it, but it's probably worth a try.
