This code is working.

<script>
   Y.on('domready', function () {
       var galleries = Y.Squarespace.GalleryManager.getGalleries();
       var duration = 4000;
       var gallery=galleries[0];
       var carousel=gallery["gallery-design"];
       var totalGroups=carousel.get('totalGroups');
       var currentGroup=0
       var container=gallery.get("container");
       var nextBtn=Y.one(gallery.get("elements.next")._nodes[0]).on("click",function(e){
           e.preventDefault();
           e.stopPropagation();
           advanceCarousel()
       })
       var prevBtn=Y.one(gallery.get("elements.previous")._nodes[0]).on("click",function(e){
           e.preventDefault();
           e.stopPropagation();
           backupCarousel()
       })
       Y.one(container._node).get('parentNode').on("mouseover",function(){
           clearInterval(myInterval)
       })
       Y.one(container._node).get('parentNode').on("mouseout",function(){
           clearInterval(myInterval)
           setMyInterval()
       })
       var myInterval;
       function setMyInterval(){
           myInterval = setInterval(function(){
               advanceCarousel()
           },duration)
       }
       setMyInterval();
       function advanceCarousel(){
           if(currentGroup==(totalGroups-1)){
               currentGroup=0;
           }else{
               currentGroup++;
           }   
           carousel.goToGroup(currentGroup);
       }
       function backupCarousel(){
           if(currentGroup==0){
               currentGroup=totalGroups-1
           }else{
               currentGroup--;
           }
           carousel.goToGroup(currentGroup);
       }
   });
</script>

In response to Paul2009, here's the new code.

<script>
   Y.on('domready', function () {
       var galleries = Y.Squarespace.GalleryManager.getGalleries();
       var duration = 4000;
       var gallery=galleries[0];
       var carousel=gallery["gallery-design"];
       var totalGroups=5;
       var currentGroup=0
       var container=gallery.get("container");
       var nextBtn=Y.one(gallery.get("elements.next")._nodes[0]).on("click",function(e){
           e.preventDefault();
           e.stopPropagation();
           advanceCarousel()
       })
       var prevBtn=Y.one(gallery.get("elements.previous")._nodes[0]).on("click",function(e){
           e.preventDefault();
           e.stopPropagation();
           backupCarousel()
       })
       Y.one(container._node).get('parentNode').on("mouseover",function(){
           clearInterval(myInterval)
       })
       Y.one(container._node).get('parentNode').on("mouseout",function(){
           clearInterval(myInterval)
           setMyInterval()
       })
       var myInterval;
       function setMyInterval(){
           myInterval = setInterval(function(){
               advanceCarousel()
           },duration)
       }
       setMyInterval();
       function advanceCarousel(){
           if(currentGroup==(totalGroups-1)){
               currentGroup=0;
           }else{
               currentGroup++;
           }   
           carousel.goToGroup(currentGroup);
       }
       function backupCarousel(){
           if(currentGroup==0){
               currentGroup=totalGroups-1
           }else{
               currentGroup--;
           }
           carousel.goToGroup(currentGroup);
       }
   });
</script>

Not yet but if you want to try feel free.

I am seeing the same issue. Had to turn it off.
