Turns out they did not swap the stereo switch lines on us, so this setting isn't really useful. Repurpose it to allow the user to force the device into headphone or line output mode. Note that settings other than "Automatic" will cause jack detection to not work. Default Automatic. Change-Id: If94499fbb8f0d92111811fe51f6107ce213b66ad
