Take a gravity reading of the sample... if its low, then it fermented. Sometimes starters won't create much, if any, of a krausen. Plus, one packet of yeast is a lot for a 1L starter, likely it just fermented out super fast.
I love the sound of an airlock bubbling in the morning. It sounds like.....VICTORY.
