Hi all, I'm wondering if anyone can explain the difference between an XRUN, and an XRUN callback. Is an XRUN callback not a matter of great concern? (It seems to me from reports in the qjackctl message window that no time is actually lost). On my system at 11ms latency i get an XRUN callback every 30 minutes or so and a true XRUN when something happens (open a jack application, for instance). Cheers, Andres
