How to monitor Blackhole audio i/o?

[han-so1omon]

I have an Ableton + Open Broadcast Studio setup using Blackhole 16 + Motu MK5 + Macbook Pro M1

I have the following aggregate device setup using Audio Midi Setup:

I have the following setup in Ableton:

I have the following setup in Open Broadcast Studio:

My question is two-part:

• How do I monitor what is going on in the Blackhole loopback interface? I would like to know if there is a signal coming in and such.
• If y'all know what is wrong with my setup directly, what is it and what would your suggestion be?

Thanks!

IMPORTANT EDIT!:
If I start Open Broadcast Studio after I start Ableton with all of my audio interface setup in the Ableton set before opening it, then it seems to work... Seems like maybe a bug in OBS, but still! I would like to know what is a good way to monitor Blackhole loopback inteface? :)
