Bug description:
After installing the latest artful kernel (Ubuntu-4.13.0-16.19), and
boot up the system with this kernel, we plug a headset to the headset
jack, then open the gnome-sound-setting, but we can not see the
headset microphone in it, there is only one internal microphone in it,
as a result we can't record the sound with the headset microphone.
This Dell machine has audio codec alc274, it needs to apply a fixup
like ALC269_FIXUP_DELL1_MIC_NO_PRESENCE.
After applying this fixup in the kernel driver, the headset mic can be
detected and works fine.
