I'm currently trying to switch my app to AudioKit. As I understand AudioKit, changing the output device during playback from headphone to build-in speaker by pulling the plug should work like a charm.
Here is a little test routine I wrote in a cocoa app:
let player = AKPlayer(url: URL(fileURLWithPath: "Some existing music file"))
func applicationDidFinishLaunching(_ aNotification: Notification) {
do {
AudioKit.output = player
try AudioKit.start()
player?.play()
} catch {
}
}
I'm getting the following error messages:
