Hi Mark, welcome from me too ...
I said "pastrugnati", an Italian dialectal word for to say alterated drivers, this way it's usually better to use the official release of them, like I have advised you previously.
Regard the foobar's setting, please note that you must set 32 bit in the Asus Asio panel setting, so you must add ( in the foobar's sub-folder named "component" )the Asio plugin in for then be able to find and choice the "Asio Asus Essence" like the output peripheral.
Editing this peripheral you will be able to set a time for all the Asus Asio panel at 32 bit, that will become so available for others applications ( like Cplay ) .
Best regards
Marco
