In general the Intel HDAudio is a pretty low qulality sound card. I so not know about the period size since I suspect that has more to do with the computer and its operation than with the sound card. Maybe if you told us why you wnat low latency someone could help. But at the 1ms sec level I think you sould need hardware assist. > > Thanks for any pointers. > > Florian > > > -- William G.
