Android Notification Channels. Disable Sound for group

Question

I have channel group

NotificationChannel notificationChannel = new NotificationChannel(GENERAL_CHANNEL_ID,
            GENERAL_CHANNEL_NAME, NotificationManager.IMPORTANCE_DEFAULT);

    notificationChannel.enableLights(true);
    notificationChannel.setShowBadge(true);
    notificationChannel.setLockscreenVisibility(Notification.VISIBILITY_PUBLIC);

    notificationManager.createNotificationChannel(notificationChannel);
    notificationManager.createNotificationChannelGroup(new NotificationChannelGroup(group, groupName));
    notificationManager.notify(code, getNotificationSingle(intent, title, message, group).build());
    notificationManager.notify(groupCode, getNotificationGroup(intent, title, message, group).build());

I want to disable the sound of notification if there are more than 2, but I still have the sound.

 @TargetApi(26)
public Notification.Builder getNotificationGroup(PendingIntent intent, String title, String body, String group) {
    Uri defaultSoundUri = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);

    return new Notification.Builder(getApplicationContext(), GENERAL_CHANNEL_ID)
            .setSmallIcon(R.drawable.ic_qlub_logo_trans)
            .setColor(colorForOreo())
            .setContentTitle(title)
            .setContentText(body)
            .setAutoCancel(true)
            .setGroup(group)
            .setGroupSummary(true)
            .setVibrate(new long[]{250, 300, 800})
            .setContentIntent(intent);

}

@TargetApi(26)
public Notification.Builder getNotificationSingle(PendingIntent intent, String title, String body, String group) {
    Uri defaultSoundUri = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);

    return new Notification.Builder(getApplicationContext(), GENERAL_CHANNEL_ID)
            .setSmallIcon(R.drawable.ic_qlub_logo_trans)
            .setColor(colorForOreo())
            .setContentTitle(title)
            .setContentText(body)
            .setGroupAlertBehavior(Notification.GROUP_ALERT_SUMMARY)
            .setAutoCancel(true)
            .setSound(defaultSoundUri)
            .setGroup(group)
            .setVibrate(new long[]{250, 300, 800})
            .setContentIntent(intent);

}

Adding Notification.GROUP_ALERT_SUMMARY doesn't help. Maybe I am trying to group them in a wrong way, but how can I disable the sound if the group has 2 and more items?

EDIT

Moving .setSound() from Notification.Builder to NotificationChannel instance and setting setOnlyAlertOnce(true) solved the problem.

when you make changes of sound or vibrate notification, you need to remove app cache, before you try some changes. did you do this? — Vadim Eksler, Aug 21 '18 at 11:39
GROUP_ALERT_SUMMARY is for notification groups, not channel groups — Florian Walther, Sep 07 '18 at 11:01
