I have also had this exact same problem. I am not running in ASIO mode I am using normal KS setup and I have been getting constant freezes for the last month. In the course of a 6 hour live stream it is not a surprise at all if I have 7 or 8 lock ups on BAL. I am been scouring the net trying to see if anyone has had similar issues to avoid posting here and looking like a whiny complainer but unfortunately I found nothing.
It is ultra annoying and worst part of all I got into the windows event manager and there is not log of an error. So I have no idea what to do.
