Hello Fiddler2007!
I don't know about the others who've had this problem, but I have already installed the 608 update, and these ASIO difficulties still persist.
I'm not sure but what it may also be why clicking on the mixer or soloing a track will cause the whole song to momentarily stop, then resume.
That is a problem that I have and I've heard others mention it as well. I have reported both of these issues to one of the PC Music technical staff. So we're probably going to have another update in the works, shortly, I hope.
Unfortunately, for me, it pretty well makes BIAB unusable at the present time.
Jim
