You de man DDDamian
I went and reviewed my settings in the Onkyo menu. My settings for analogue, S/PDIF and HDMI were pretty much the same - Direct. The settings for all the HD formats were set to match the source data, DTS HD Master, Dolby TrueHD and DSD etc.
But (due to some omission on my part), there on page two of the source settings, was the culprit. The setting for Multichannel PCM was "Last Valid" Once I set it to "Direct", all was well with WASAPI - all the channels mapped correctly to the relevant speakers. What I can't quite figure out is why the DirectSound mixer on Windows was giving me full 5.1 effect on my system (with a display of MCH 5.1 on the amplifier), but the same source file on WASAPI was causing the amp to trigger some form of blending of the two back channels onto the two front speakers, no doubt caused by the "Last Valid" setting on the amp. All is working as it should now, phew! It was all so much easier in the old analogue days!
