It reminds me of the discussion we had about jack labelling (for HDA or everyone? I do not remember), where we ended up having
- physical location (left side, internal, docking station)
- type (headphone, speaker)
- channel map (front, rear, c/lfe)
Maybe that's where this discussion is heading as well? I like the idea of having the same TLV description for jacks, mixer controls and PCM channels, maybe that could work for all but the most exotic cases?
(Where exotic means unusual hw on both the pro-audio and the embedded side)
Or perhaps what we want to do here is define the channel mapping in terms of saying "I'm connecting to this input/output" and then use the jack interface to describe all inputs and outputs rather than just jacks (making sure it's easy to see which ones can change state)?
