Sonar 8.5 producer delay?

I have sonar 8.5 producer and there is a slight delay when I record onto a track from when I play to when I hear it. That isn't too big of a deal I just mute while recording, but when I record on a second track while in sync with track 1 it seems to be fine but in playback the second track lags a second after the first. What causes this delay?
