Mac Mini, M-Audio MobilePre Latency problem!

[nms]

I have the M-Audio MobilePre Breakout Box and when i plug my guitar in, open garageband and test the garageband amp settings there is quite a bit of latency.

Ok, i lie, there is absolutely no latency......until i plug in headphones/hi-fi into the lineout on my Mac Mini, THEN the latency begins.

If anyone thinks they can help, has any more questions or has the same problem....please post! You know the drill!

what you're hearing is your signal after two rounds of conversion (analog->digital, then digital->analog). conversion takes time. there's no way to hear the processed signal w/o latency. what's usually done is to split off the analog signal before it hits the first converter and monitor that. typically, when an interface is marketed with "no latency monitoring", that's what it's doing internally.
