The mixerctl options (-a -v) for the STAC9221D (0x8384/0x7683) codec are
as follows:

inputs.dac02.mute=off [ off on ]
inputs.dac02=126,126 delta=2
inputs.dac03.mute=off [ off on ]
inputs.dac03=126,126 delta=2
inputs.dac04.mute=off [ off on ]
inputs.dac04=126,126 delta=2
inputs.dac05.mute=off [ off on ]
inputs.dac05=126,126 delta=2
outputs.green0a.dir=output [ input output ]
outputs.green0a.boost=on [ off on ]
outputs.pink0b.dir=input [ input output ]
outputs.blue0c.dir=input [ input output ]
outputs.green0d.dir=output [ input output ]
outputs.green0d.boost=off [ off on ]
outputs.other0f.dir=input [ input output ]
outputs.other10.source=dac08 [ dac08 sel17 widget19 ]
inputs.sel12.source=other0e [ other0e pink15 other0f pink0b blue0c
green0d green0a ]
outputs.sel12=255,255 delta=63
inputs.sel13.source=pink15 [ other0e pink15 other0f pink0b blue0c
green0d green0a ]
outputs.sel13=255,255 delta=63
inputs.beep14=85 delta=85
outputs.volume16=255 delta=2
inputs.sel17.sel12.mut=off [ off on ]
inputs.sel17.sel12=109,109 delta=18
inputs.sel18.sel13.mut=off [ off on ]
inputs.sel18.sel13=109,109 delta=18
inputs.usingdac=02 [ 02 0304 05 08 1a ]
record.usingadc=adc06 [ adc06 adc07 adc09 ]

I was wondering if there is anything here which is worth changing? I
have played with the outputs.* settings without any luck. Is this a case
of an unsupported/semi-supported codec which needs development and, if
so, would it be worthwhile diving into the azalia driver code?
