refer to the maintenance and service guide

When a device is plugged into the Microphone/Headph
one Connector, a dialog box will pop up asking if
you want to use the connector for a microphone Line-In
device or a headphone. You can reconfigure the connector
at any time by double-clicking the Audio Manager icon in the Windows
taskbar


 the hardware reference guide and Illustrated Parts and Service map
 microphone jack and headphone jack

it seem not support TRRS headset

Do the icon really show a headset ( headphone with mic) ?
