Do you have an In point set, or does this happen with no marks in the Timeline? If the latter, you might try resetting preferences: FAQ: How to reset (trash) preferences in Premiere Pro?
What kind of audio file? (I recommend using only .wav files.)
I tried both Shift-Option & Option while launching Premiere Pro. The problem still exists. The problem exists on all audio file types, even WAV & AIFF.
I think I just found the problem. When you apply Essential Sound FX the audio scrub is no longer accurate.

That may be because the effects are too much to process real time.
