System Preferences
QLab can only use audio devices that are available on your computer. On a Mac, you can see all the available devices by going to System Preferences, then clicking on Sound. Under the Output tab you’ll see which devices are connected to your computer and which one is currently in use. Here you’ll see my internal speakers, my Dante virtual sound card, an external Scarlet 2i2 device that I use for audio recording, and even some Apple TVs that I could connect to over airplay.
QLab can output to almost any device that appears in this list. And more importantly, it can utilize several devices at once; it doesn’t even matter which one you have selected as default in your System Preferences.
