this is speciak feature of HDA driver which copy front signal to all output
jacks

seem bug in alsa driver if your front jack has no sound 

as pulseaudio provide profiles: stereo surround40


the grey jack shoul be muted by pulseaudio when you select front profile when
you play stereo through pulseaudio
