Hello,

I would recommend using one of the Core Audio plugins to stream your Blackhole data as an actor: AUSoundInput 

For me it works perfectly (for example I output Movie Player sound from Izzy into Blackhole, and grab it back in the same patch through this actor, it enables sound treatment of movies that the Movie Player doesn´t offer -yet?- in izzy) and I never need to reconfigure it as Blackhole remains the input parameter no matter what happens.

the mapping of channels offered in the actor works fine!
