What if connecting a headphone jack instead of a headset?

Does the device have another mic (internal mic or whatever)?
The mis-detection of mic jack won't be a big problem if there is a
single mic input, but if there are two, the driver may switch
automatically per jack status, thus it becomes a real problem.
