I have a custom mp3 sound that I use on my notifications. It works fine on all devices below API 26. I tried to set the sound on Notification Channel also, but still no work. It plays the default sound.

NotificationCompat.Builder builder = new NotificationCompat.Builder(this, channelId)
            .setAutoCancel(true)
            .setSmallIcon(R.drawable.icon_push)
            .setColor(ContextCompat.getColor(this, R.color.green))
            .setContentTitle(title)
            .setSound(Uri.parse("android.resource://" + getPackageName() + "/" + R.raw.notification))
            .setDefaults(Notification.DEFAULT_VIBRATE)
            .setStyle(new NotificationCompat.BigTextStyle().bigText(message))
            .setContentText(message);
        Notification notification = builder.build();
        NotificationManager notificationManager = (NotificationManager)getSystemService(Context.NOTIFICATION_SERVICE);
        if (android.os.Build.VERSION.SDK_INT >= android.os.Build.VERSION_CODES.O) {
            NotificationChannel channel = new NotificationChannel(channelId, channelName, NotificationManager.IMPORTANCE_DEFAULT);
            AudioAttributes audioAttributes = new AudioAttributes.Builder()
                    .setContentType(AudioAttributes.CONTENT_TYPE_SONIFICATION)
                    .setUsage(AudioAttributes.USAGE_NOTIFICATION_RINGTONE)
                    .build();
            channel.setSound(Uri.parse("android.resource://" + getPackageName() + "/" + R.raw.notification), audioAttributes);
            notificationManager.createNotificationChannel(channel);
        }
        notificationManager.notify(1, notification);

You may have created the channel originally with default sound. Once channel is created it cannot be changed. You need to either reinstall the app or create channel with new channel ID.
