Since "Front" controls headphones as well on these two codecs, they should be labeled "Master Front" in order to be handled correct by PulseAudio.
Well, "Front" doesn't mean the physical output but rather the output channels. So, it doesn't conflict with the fact that this control actually changes all outputs, as long as the output jacks are of front channels. In that sense, even "Surround" is also a sort of Master control.
That being said, I'm not happy with this rename. If any, we should try to get rid of unnecessary front volume control. But, just because PA gets confused doesn't sound like a right reason.
Could you give the alsa-info.sh output for checking what mixer elements are created?
As you know PulseAudio needs consistent naming of volume controls, and this is not expressed clearly enough in the docs, so, what would you call a volume control that controls a front-line-out, but does not control a front-speaker or a front-headphone? PulseAudio assumes that if a control is named "Front", it does just that. So that's why I would prefer a rename to "Master Front".
As for alsa-info output, I believe anything in hda-emu/codecs/alc861vd-* would do, as they have nsteps=0 on NIDs 0x0c - 0x0f.
