You are dead on. I assumed (for whatever reason) that since those
boxes were disabled, that their state of default check-ed-ness would
be ignored. That is clearly not the convention. So, I switched to a
device that enabled E-AC-3, TrueHD and DTS-HD, unchecked them, and
then went back to my original ALSA:hdmi:CARD=NVidia,DEV=1 -- And
