That is interesting, thanks, Simon. The only statement I could find that seems to relate here is this one:

WASAPI can be used in two different modes: shared or exclusive. In FlexASIO, the wasapiExclusiveMode option determines which mode is used. The two modes behave very differently; in fact, they should probably be seen as two separate backends entirely.

As relates to BIAB, does that mean that the WAS driver choice in BIAB, which has never worked for me, might work if I 'allowed my soundcard driver to take exclusive control'? I might try it and see.
