I'm still having problems with "division" error and biab freezing. It works for a while. I have an external Audio Box and using ASIO Audio Box driver. I've tried them all. They all work for a bit then I start getting the error again.
I would try Return To Factory Settings > All, then set the Audio Settings to MME and try hard to see if you can reproduce the issue. Hopefully that will assist to narrow the item down.
