Well, the rest of the Mini is doing great, but the azalia's not working.
No errors or anything, just no sound.

The mixerctl output looks a bit odd:

$ mixerctl -a
inputs.dac02.mute=off
inputs.dac02=168,168
inputs.dac02.lrswap=off
inputs.dac03.mute=off
inputs.dac03=168,168
inputs.dac03.lrswap=off
inputs.dac04.mute=off
inputs.dac04=168,168
inputs.dac04.lrswap=off
inputs.dac05.mute=off
inputs.dac05=168,168
inputs.dac05.lrswap=off
outputs.green0a.dir=output
outputs.green0a.boost=on
outputs.unknown0b.dir=output
outputs.unknown0c.dir=output
outputs.unknown0d.dir=output
outputs.unknown0d.boost=off
outputs.blue0f.dir=input
outputs.white10.source=dac08
outputs.white11.eapd=off
inputs.sel12.source=unknown0e

inputs.sel13.source=unknown15
outputs.sel13=63,63

inputs.sel17.sel12=109,109
inputs.sel17.lrswap=off

inputs.sel18.sel13=109,109
inputs.sel18.lrswap=off
playback.mode=02030405
record.mode=0607

This is the kind of thing that makes me wonder whether something went
wrong during configuration.
