hint.hdac.0.config="gpio0"
hint.hdac.0.config="gpio1"
hint.hdac.0.config="gpio2"
hint.hdac.0.config="gpio3"

hint.hdac.0.config="gpio0, gpio1"
hint.hdac.0.config="gpio0, gpio2"
hint.hdac.0.config="gpio0, gpio3"

hint.hdac.0.config="gpio1, gpio0"
hint.hdac.0.config="gpio1, gpio2"
hint.hdac.0.config="gpio1, gpio3"

hint.hdac.0.config="gpio2, gpio0"
hint.hdac.0.config="gpio2, gpio1"
hint.hdac.0.config="gpio2, gpio3"

hint.hdac.0.config="gpio3, gpio0"
hint.hdac.0.config="gpio3, gpio1"
hint.hdac.0.config="gpio3, gpio2"

I have tried all 16 combination ( 1 by 1), I check the sound with this
command *cat /dev/random > /dev/dsp*.  with hw.snd.default_unit=1. And I do
try with/without the earphone.
all of them just them same, *cant* hear any sound.
