And there is an reported update released for that as well. http://arstechnica.com/journals/apple.ars/2007/07/03/apple-revises-10-4-10-t o-fix-audio-issues-releases-separate-update http://docs.info.apple.com/article.html?artnum05533 The audio update should be available via software update as well. Hope that helps! I'll keep digging on this USB audio latency though... I can't really spring for a firewire unit right now. :-( And we had a MOTU 828 (original) that recently died. Doh! Micha
