I don't know when you lose audio and when you don't. I actually asked an almost identical question on the Jack Developer's list about 60 days ago and got a long thread of answers and info in return. If you have some time then scan their archives and find it. I think it's and interesting read. Other than that all I can say is that xruns are never good and you need to adjust until you never get them at critical times.
