Yes, please compile a kernel defined with AZALIA_DEBUG and file a PR,
including the mixerctl/audioctl output, dmesg, and what you'd like to
see fixed.  I wish I could help you myself, but it's beyond me. :(

From what I see here, though, the driver is telling you that it
doesn't know what to do with ONE of your codecs (codec 1); codec 0 is
fine.
Have you tried playing around with all of the mixer settings?
Sometimes their names can be misleading.  On my STAC9221, the DAC
output volume is technically an "input", so I have to raise the volume
for inputs.dac02 to hear anything.

"The frivolity and boredom which unsettle the established order, the
vague foreboding of something unknown, these are the heralds of
approaching change.  The gradual crumbling that left unaltered the
face of the whole is cut short by a sunburst which, in one flash,
illuminates the features of the new world."  --G.W.F. Hegel,
