如何在android中设置带有通知的自定义声音

我已将notification.mp3文件放入res->raw文件夹。但当触发通知时，它会产生默认声音。我从firebase推送通知收到通知，它正在工作。 这就是我发出通知的方式

    Uri soundUri = Uri.parse("android.resource://" + getPackageName() + "/" + R.raw.notification);
    
    NotificationCompat.Builder builder = new NotificationCompat.Builder(getApplicationContext, CHANNEL_ID);
            builder.setCustomBigContentView(notificationLayoutExpanded);
            builder.setSmallIcon(R.drawable.ic_notifications);
            builder.setContentTitle(message);
            builder.setSound(soundUri, AudioManager.STREAM_NOTIFICATION);
            builder.setAutoCancel(true);
            builder.setPriority(Notification.PRIORITY_HIGH);
            
            Intent intent = new Intent(getApplicationContext(), HomeActivity.class);
            intent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
 

        PendingIntent pendingIntent = PendingIntent.getActivity(
                getApplicationContext(),
                0,
                intent,
                PendingIntent.FLAG_UPDATE_CURRENT
        );
        builder.setContentIntent(pendingIntent);

        NotificationManager notificationManager = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
        notificationManager.notify(0, builder.build());
