But the problem that keeps popping up on the lists is that people who are not doing live sound, have cards that do hardware monitoring, and don't need to use a tiny buffer size waste their time trying to get the minimum buffer size because they think they need to get 2-3ms latency. So, they get xruns out the wazoo and wonder how to fix it. In this case he *needs* a small buffer size though since he's doing, essentially, a live application.
