watchOS live audio stream from watch

Hi,

I would like to stream live audio (hls) from watch itself, our app can start stream on paired device, but when phone is not near by i want to start streaming on watchos (just like spotify or Apple music app) I watched the 2019 wwdc video about streaming and also looked to the documentation

Documentation : https://developer.apple.com/documentation/watchkit/storyboard_support/playing_background_audio

I can present the route controller to select output, but for example after selecting Air Podcas, stream did not start..

Here is the code: (I have enabled background mode audio)

                                do {
                                    try  AVAudioSession.sharedInstance().setCategory(.playback, mode: .default, policy: .longFormAudio, options: [])
                                }
                                catch {
                                    print("no audiosession!")
                                }
                                     
                                AVAudioSession.sharedInstance().activate(options: []) { success, error in
                                    dump(success)
                                    dump(error)
                                    DispatchQueue.main.async {
                                        if let streamURL = moduleItem.media?[0] as? String {
                                            dump(streamURL)
                                            let asset  = AVURLAsset(url: URL(string: streamURL)!, options: nil)
                                            let item = AVPlayerItem(asset: asset)
                                            let player = AVQueuePlayer(playerItem: item)
                                            player.play()
                                        }
                                    }
                                }
