Hi, I suspect this is normal behaviour as it happens in Logic too, but wanted to check.
When running Cubase 6.5.3 with CoreAudio / Built-in soundcard on my Macbook Pro early 2011 model. I hear all music playback stop for 1-3 s then resume sometimes. It happens only under CPU / memory stress on a buffer of 512. If I increase the buffer size it helps, but can still happen.
Is this normal ?
I never get it while using my Focusrite interface.
