Android 8-Benachrichtigungen setSound funktioniert nicht

Ich habe den folgenden Code, höre aber immer den Standard-Android-Sound. 

        // create  channel
        NotificationChannel channel = new NotificationChannel(Android_CHANNEL_ID,
                Android_CHANNEL_NAME, NotificationManager.IMPORTANCE_DEFAULT);
        // Sets whether notifications posted to this channel should display notification lights
        channel.enableLights(true);
        // Sets whether notification posted to this channel should vibrate.
        channel.enableVibration(true);
        // Sets the notification light color for notifications posted to this channel
        channel.setLightColor(Color.GREEN);
        // Sets whether notifications posted to this channel appear on the lockscreen or not
        //channel.setLockscreenVisibility(Notification.VISIBILITY_PRIVATE);
        channel.setLockscreenVisibility(Notification.VISIBILITY_PUBLIC);

        Uri uri = Uri.parse("Android.resource://"+this.getPackageName()+"/" + R.raw.aperturaabductores);

        AudioAttributes att = new AudioAttributes.Builder()
                .setUsage(AudioAttributes.USAGE_NOTIFICATION)
                .setContentType(AudioAttributes.CONTENT_TYPE_SPEECH)
                .build();
        channel.setSound(uri,att);

Dies ist mein Sound pablomonteserin.es/aperturaabductores.wav

Ich habe versucht, den Unterschied zwischen Ihrer und meiner Sounddatei zu erkennen. Ich habe Audacity-Software verwendet .. Ihre Audiodatei hat eine Abtastrate von 22050 Hz, während die von mir verwendeten Audiodateien bei 44100 Hz abgetastet werden. Also habe ich Ihre Audiodatei-Abtastrate auf 44100Hz konvertiert und als Benachrichtigungston verwendet. Jetzt gehts.

Das Problem liegt bei der Sounddatei. Möglicherweise handelt es sich um eine neue Änderung in Android O, da es auf älteren Android-Versionen einwandfrei funktioniert.

So resample -  enter image description here
