Actually its worse than I thought... Picture and audio output through the Kona drifts out of sync. On in FCP it stays in sync.
Checked the card / slot arrangement and speed but that is fine, anyhow same setup that has been working for months.. only change is that we just updated OS X, ATTO R380 drivers, and the Kona drivers. I guess one of those gave the system indigestion. Any suggestions? Reinstall all of those? hmm. OK. Anyone else get this?
