桌面Safari下Flutter just_audio蜂鸣播放异常问题

我正在开发模拟医疗监护仪功能，需要播放时长250ms、频率30-300Hz的蜂鸣声。测试多个音频包后选用just_audio，该包在除桌面Safari外的平台均正常运行。

音频播放列表

final playlist = ConcatenatingAudioSource(children: [
    AudioSource.uri(Uri.parse('asset:///assets/audio/beepfiles/98.wav')),
    AudioSource.uri(Uri.parse('asset://assets//audio/beepfiles/96.wav')),
    AudioSource.uri(Uri.parse('asset:///assets/audio/beepfiles/94.wav')),
    AudioSource.uri(Uri.parse('asset:///assets/audio/beepfiles/92.wav')),
  ]);

音频播放器初始化

Future<void> _initAudio() async {
await player.setLoopMode(LoopMode.one);
final session = await AudioSession.instance;
await session.configure(const AudioSessionConfiguration.speech());

try {
player.setAudioSource(playlist);
} catch (e) {
debugPrint("Error loading audio source: $e");
}
}

带心率变化延迟的蜂鸣播放函数

void playBeeps(WidgetRef ref) async {
    var obs = ref.watch(obsProvider);
    obs.whenData((obs) async {
      Future.doWhile(() async {
        var obs2 = ref.watch(testLocalObsProvider);
        int hr = obs2.heartRate;
        int sats = obs2.saturationsO2;
        bool audioIsMuted = ref.read(muteAudio);
        int track = (50 - ((sats / 2).round())).clamp(0, 15);
        player.seek(Duration.zero, index: track);
        await Future.delayed(
            Duration(milliseconds: ((60 / hr) * 1000).round()));
        player.play().catchError((e) {
          debugPrint(e);
        });
        await Future.delayed(const Duration(milliseconds: 250));
        player.pause().catchError((e) {
          debugPrint(e);
        });
        return !audioIsMuted;
      });
    });
  }
