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?
What do you mean "front" in this context? Is it the front 2 channels out of 4.0 or 5.1 output? Or do you mean the physical location of the output? Front/Surround/Center/LFE are the former case. They are controls independent from the physical output locations (per definition).
I guess this confusion came up because of the mix-up with front channel and front panel. We've used "Front Mic" in some places, for example, which increases the confusion.
Good point. I think the reasoning so far is to refer to channels for output and location for input.
Anyway, what I meant was "Front" channel (not location), so let me rephrase my question into two:
1) If I find a volume control (or mute switch) labeled "Front", should I assume that it controls, or does not control, headphone output? How about internal speakers?
2) Assume I have a volume control (or mute switch) which controls only the front line-out, not headphones, and not speakers. How should I name it?
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.
Yeah, the output with your first patch would be helpful.
Unfortunately I don't have access to the actual hardware at the moment, so I'm attaching a codec dump from the hardware before the patch. Running it against current HEAD, with today's patch from Kailang in, probably makes hda-emu take the wrong code path (since hda-emu can't read proc coefs).
