On the Dell machines with codec whose Subsystem Id is 0x10280640, no external microphone can be detected when plugging a 3-ring headset. If we add "model=dell-headset-multi" for the snd-hda-intel.ko, the problem will disappear.
The codec (Vendor ID: 0x10ec0255) on the machine belongs to alc_269 family.
