Hey newbie, hope this helps ya! The USB Audio panel under the Utility section has a “Play” and “Record” feature. On the Play area there is an option to “Assign” where you want the audio to be sent out. For example, I’m sending the audio down inputs 57/58. After you find on the console where the audio is being sent you can access the processing of the assigned fader and turn up the “Trim” level. If for some reason it still isn’t loud enough, try sending it to a “DCA” then have it routed to your “Main Bus” out. If this isn’t an option for you, just throw a compressor on one of the inserts and boost the heck out of it with “Make Up” or “Post Trim”. Hope this help!
