Ian, I use WDM in BiaB and ASIO in Sonar. This way I can have both on the screen at the same time. Note that I only record in Sonar and never in BiaB; this is the way I suggest your workflow to be. However if you need to record in BiaB then you can use ASIO in BiaB and WDM in Sonar.

WDM has way to much latency thus I can not record with it.

When you are at the checkout line and they ask if you found everything say "Why, are you hiding stuff?"

64 bit Win 10 Pro, the latest BiaB/RB, Roland Octa-Capture audio interface, a ton of software/hardware
