when headphone is plugged , driver set the pin ctls of four line out jacks to zero

CTL Notify: Front Headphone Jack:0, mask=1
JACK report Front Headphone, status 1
JACK report Rear Mic, status 0
JACK report Front Mic, status 0
JACK report Line, status 0
JACK report Line Out Front, status 0
JACK report Line Out Surround, status 0
JACK report Line Out CLFE, status 0
JACK report Line Out Side, status 0

driver update headphone jack status and send ctl notify to user space

when pulseaudio receive the hctl event, pulseaudio mute the four line out playback switches
