Hi,
thinking of the problem about shared volume controls again, I stumbled on a case where your suggested solution doesn't work well. Namely, when a headphone volume is shared for two headphones (one on the laptop and one on the dock), how should it be named? One is "Headphone" and another is "Dock Headphone". That's a bit tricky.
So, in the end, we need the mapping representation somehow more explicitly than the control name.
Thoughts?
In practice, it seems like we more often than not share DAC for all headphones. Also it is very common today that a jack called "Front Headphone" has a volume control called only "Headphone".
That's the status quo. As a result we have only one headphone path in PulseAudio for all types of headphones.
OK, so "Headphone" volume should be handled by both "Headphone Jack" and "Dock Headphone Jack" detections? Then it's fine. I thought this wasn't the case (from my memory dealing with an old bug report).
Yes. The "Dock Headphone Jack" name was added quite recently though, so it's only in git master right now.
