To be honest, I think this is a fools errand.
There are MANY devices with large numbers of channels. The way these
devices are connected to speakers is not defined anywhere. You can
also forget jack-sensing and stuff like that. Even sitting right next
to me is a fireface 400, with 18 channels of output. You have no idea
how this is wired up in my office/studio, and there's nothing you can
do to find out except ... ask me.
the "output modes" in audio/MIDI setup have essentially nothing to do with this.
