I am trying to modify the mixer implementation in my wavedev pdd to
reflect some custom HW modifications. I have a audio jack that can be
used as the headphone output via an amp from the codex or by changing
some GPIO lines it can serve as a line input or mic input. Also I can
redirect the input to an internal speaker by putting the device in a
"bypass" mode. So I need to set a couple of "modes" if you will for my
audio device. This certainly seems like a mixer feature but doesn't
seem to fit in any of the predefined WPDMX_ type of messages? Any
thoughts about what makes sense?
