Thanks, Lars, for the good pointers! I will check that out.
Is there also a way to map GPIO to a control which then appears e.g. in
alsamixer? That would be useful for the mic/line selection.
Rather than exposing the GPIO itself you'd expose the logical function of
the GPIO. E.g. in your case a ENUM control that allows to switch between
microphone and capture and in the background this sets the GPIO according to
the selection.
I understand that, my question was more how to hook the enum to a
function rather to a codec register?
Thanks
Petr
