Here is analysis of the ABC Aust transmission sample I just took. Although this actual program does not have Audio Description, the 2nd track is active anyway and running same "main" audio as Track 1.
It would appear Channels is defaulting to Track 2 Audio - because Track 1 no longer shows up as selectable for whatever reason. I'll get proper samples when I can or hopefully @Maximus will beat me to it.
