[alsa-devel] Shared volume control again

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?
