Converting an existing iOS app to MacOS in Xcode 11.1 (MacBook OS Catalina 10.15.6). The app plays a selection of recorded audio. Using MyMac as output device from Xcode, the app 'plays' fine through MacBook speakers but getting error messages in the console:

AggregateDevice.mm:790 couldn't get default input device, ID = 0, err = 0!

AVAudioSession_MacOS.mm:351:-[AVAudioSession createPortsfromAggregateDevice:]: No Ports available returning empty

Are these just 'bugs'?
