I've been using both a POD (original; line outs into line in of soundcard)) and a Guitaport (USB), and I notice latency issues with both. I've also noticed similar results when running my Microcube into the Line In of the soundcard as well as when mic'ing cabs into various preamps in the past. Recently however, o test this, I record something really simple and then play over that playing the exact same thing; I play it synced up, but when I listen to it afterwards, the 2nd recording is slightly behind the first. Is there anyway to correct this? I'd say that maybe a better sound card is in order, but with the Guitarport, it is my understanding that it takes the place of the soundcard. So is there no way to fix latency with the GP? What about the POD?
