What I'd expect to happen here is that for multi function jacks we
create a control per function if the controls are valid.
Ok, so the idea is just to change the control to type integer instead
of boolean, right?
Because as you say, the user will be able to check the type of jack
based on the status value, right?
It might be more idiomatic and more compatible with userspace to create
multiple controls for the jack, there was some discussion of this in the
past I think but I can't remember the result.
Yes. If there's only one function supported the current code is fine
but for multiple functions it's going to discard useful information.
So, what do you suggest to do that? I'm not sure if I understand what
you are saying.
When you mean function, do you mean the SND_JACK_BTN_n or the the jack
types, such as SND_JACK_HEADPHONE, and so on?
The jack types, the buttons definitely sohuld be going up as input
If a codec creates a jack type SND_JACK_HEADSET (= SND_JACK_HEADPHONE
| SND_JACK_MICROPHONE). It should be created two controls, name +
"Headphone Jack" and name + "Microphone Jack"? If so, what about the
status to report? How to know which control to report?
The drivers report a bitmask for status.
