Is this normal? 1 - When I play music via the computer speakers and I plug in my headphones, the audio continues to come through the computer speakers for a few seconds after plugging in the headphones. On my white 2007 macbook, the change was instantaneous, i.e. the very second I put in the headphones, the audio would stop coming out of the computer speakers. Try plugging in headphones and immediately after pressing the volume up key - when I do this, I can still hear the volume up key via the computer speakers during the next seven-nine presses (depending on how fast you press) before the sound actually comes through the headphones Originally I thought the audio switch delay was from a defective computer, but but I'm on my second rMBP (first was replaced due to ghosting) and both had this same audio delay.
