At this point, plugout and plugin the headset will get the correct headset type as OMTP. The reason for the failure of headset type recognition is that the sound card creation will enable the VREF voltage of the headset mic, which interferes with the headset type automatic detection circuit. Plugout and plugin the headset will restart the headset detection and get the correct headset type. The patch is disable the VREF voltage when the headset is not present, and will enable the VREF voltage when the headset is present.
