Choose Default Out CHANNEL for OS X Audio I need to get my default audio output to outputs 3/4 of my audio interface. What is the easiest way to do this? Do I need Soundflower (and will it even work)?
I'm not 100% sure if this will work, but have you tried the Audio MIDI Setup? Its located in Applications &gt; Utilities &gt; Audio MIDI Setup.app Your USB audio device should be listed in the left hand pane and from there you may be able to route the audio as you wish
