I checked your manual - for the "Direct" mode there is a footnote that basically says (if I am reading right) - the number of channels being played (including the subwoofer) depends on the number of channels in the original source.
So, at least for Direct, if there are only two channels for an 'old fashioned' stereo LP or CD, then that's all you get - two channels and therefore, no sub.
Maybe they forgot that footnote for "Stereo" mode?
