Hi jbaileyUnfortunately this didn't work, it seems to only be called when the watch is inactive for awhile or if a diferent app is brought to the front. Any other suggestions?Andrew

Hi jlilest002I tried your suggestion and another line of code :- AVAudioSession.RouteSharingPolicy.longFormAudio but unfortunately it didn't work. I am not very experienced in programming so maybe I am inserting this code in the wrong place, it's just before the code to define the audio path and "try AVAudioPlayer(contentsOf: urlPath)" let session = AVAudioSession.sharedInstance() // AVAudioSession.RouteSharingPolicy.longFormAudio do { // try AVAudioSession.session.RouteSharingPolicy.longFormAudio try session.setCategory(AVAudioSession.Category.playback, mode: .default, policy: .longFormAudio, options: []) } catch let error { fatalError("*** Unable to set up the audio session: \(error.localizedDescription) ***") }Andrew

It has been suggested to post some of my code. The first snippet below only gives a warning that "longForm" is depreciated, so I dont know what to do and this is commented out. let session = AVAudioSession.sharedInstance() AVAudioSession.RouteSharingPolicy.longFormAudio do { // try AVAudioSession.session.RouteSharingPolicy.longFormAudio try session.setCategory(AVAudioSession.Category.playback, mode: .default, policy: .longForm, options: []) } catch let error { fatalError("*** Unable to set up the audio session: \(error.localizedDescription) ***") }This is the code I am using and it plays the .aiff files without problems, except the sound stop playing when wrist lowered. let pathOne = Bundle.main.path(forResource: audioOneFile, ofType: ".aiff")! let urlOne = URL(fileURLWithPath: pathOne) // = 1 let pathTwo = Bundle.main.path(forResource: audioTwoFile, ofType: ".aiff")! let urlTwo = URL(fileURLWithPath: pathTwo) // = 2 do { self.audioOnePlay = try AVAudioPlayer(contentsOf: urlOne) self.audioTwoPlay = try AVAudioPlayer(contentsOf: urlTwo) } catch { // couldn't load file :( assertionFailure("Failed creating audio player: \(error).") } DispatchQueue.main.async { // Start by speaking first phrase self.audioOnePlay.play() // These wait until the PRVIOUS phrase has been played DispatchQueue.main.asyncAfter(deadline: .now() + oneDurationNumber) { self.audioTwoPlay.play() } // Audio Two }Any help would be gratefully received.Andrew
