 I see something similar on a Dell Precision M4300.
 I built current kernels with azalea and hdaudio
 (otherwise identical).
 A diff of dmesg.boot for the two kernels is

 The timecounted difference is obviously just noise, the only other meaningful
 difference is the audio.   Noth kernels are monolithic (no modules).
 Of itself, this looks OK, but using azalea, mixerctl -av claims:
 outputs.black0a.source=dac10  [ dac10 dac11 ]
 outputs.black0a.dir=output  [ input output ]
 outputs.black0a.boost=off  [ off on ]
 outputs.black0b.source=dac10  [ dac10 dac11 ]
 outputs.black0b.dir=output  [ input output ]
 outputs.unknown0c.dir=output  [ input output ]
 outputs.unknown0d.dir=output  [ input output ]
 outputs.unknown0d.boost=off  [ off on ]
 inputs.dac10.mute=off  [ off on ]
 inputs.dac10=126,126  delta=2
 inputs.dac10.lrswap=off  [ off on ]
 inputs.dac11.mute=off  [ off on ]

 inputs.dac11.lrswap=off  [ off on ]
 inputs.sel19.source=  [ black0b unknown0c unknown0d black0a ]

 outputs.volume24=126  delta=2
 playback.mode=10  [ 10 1110 1f ]
 record.mode=12  [ 12 13 20 ]
 Whereas with hdaudio I see a very similar result as asau@ indicated:
 outputs.master=254,254 volume delta=2
 inputs.dac=254,254 volume delta=2
 inputs.beep=255,255 volume delta=64
 inputs.reclvl=0,0 volume delta=51
 outputs.dacsel=DAC00  { DAC00 }
 record.source=ADC01  { ADC01 }
 which seems a little unlikely!
 Note, that azalea doesn't work either on this system, I never bothered about
 that as I assumed that if I ever really needed it, I'd eventually find a
 combination of mixerctl settings that did something (managed that with the
 wife's vaio).   It never bothered me as I prefer my computers to remain quiet!
 I can do any more testing that might help, if requested (I don't generally run
 current - those boots were purely for this test)
 I once did the dot graph building magic with azalea debug output, that
 just left me more confused than before I started!
