@AntEater and @timlance I came across this topic searching for how to output audio to AirPlay (or even anything but the internal speakers on my MacBookAir) and I finally figured it out and am posting my findings here for anyone else who might search and find this topic: Preferences/ Backend/ Under "Audio Output": Output: "Output to a sound card on MacOS" Device: "Automatically select" Of course, you can select any of the available devices under the "Device:" menu, but the "Automatically select" option appears to follow what output option (including AirPlay speakers) I have currently selected under my "Sound" menu options on the menu bar. Note - any changes in preferences didn't go into effect until I stopped and started whatever I was listening to. Great job developers!!
