Hey guys, I can't get sound out of my laptop (MacBook Pro 2012) via USB into the D30. Laptop recognizes D30, but still no sound ..I've gone into system preferences, sound, output, and have selected it. I also went into Audio MIDI setup, found the D30 there and tried to enable it with no luck ..is there something goofy I'm missing in these menus to enable it or what? Thanks.
