Hi Johnny!
Set it up by following the instructions on that page. 🙂
The only difference I can see is that once you’ve spawned the mixer record properties, you’ll have to go to Options and Properties, select Recording, and then select the actual sound card, so that you’ll be controlling the sound card instead of Breakaway Pipeline.
If OTSAV properly records the audio from the sound card, and then plays it into Breakaway Pipeline the same way it plays music, everything will just magically work.
Best,
