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)?
That's an interesting idea. The possible drawback is that it would require all drivers that want to use this to implement jacks also.
I'm not sure that's a big deal, we should be able to make the fixed data case easy enough to do.
In the ctljack interface for HDA, we already describe all inputs and outputs - with the nonchangable ones having the additional "Phantom" suffix, so the result becomes e g "Internal Mic Phantom Jack".
Which of course is also replicated with the calls into the original jack API.
