did you find headset mic jack or headset mic phantom jack in codec info
using dell headset model?


In PulseAudio ports will show up with the following names:
   Headphones - analog-output-headphones
   Headset mic - analog-input-microphone-headset
   Jack in mic-in mode - analog-input-microphone

   However, since regular mics also show up as analog-input-microphone,
   we need to check for certain controls on alsa mixer level too, to know
   if we deal with a separate mic jack, or a multi-function jack with a 
   mic-in mode (also called "headphone mic"). 
   We check for the following names:

   Headphone Mic Jack - indicates headphone and mic-in mode share the same jack,
     i e, not two separate jacks. Hardware cannot distinguish between a
     headphone and a mic.
   Headset Mic Phantom Jack - indicates headset jack where hardware can not
     distinguish between headphones and headsets
   Headset Mic Jack - indicates headset jack where hardware can distinguish
     between headphones and headsets. There is no use popping up a dialog in
     this case, unless we already need to do this for the mic-in mode.
