Changing only one device in aggregate

[autoditactics]

I'm using SoundFlower with this, and I want the volume set for SoundFlower to be always be at max. If it's not, then recordings get really quiet. In other words, I only want changes to volume to affect the other output device in the aggregate device and not SoundFlower. Is there a way to do this? If not, I think it's a good idea to add this as an option, maybe by only changing the master device's volume in AudioManager.swift if the option is set.
