I have a brand new 2011 MBA 13" and when I plug in an audio cable into the headphone port, it's like it doesn't recognize it until about 4 seconds later. I'll plug in the audio cable into the computer and the sound keeps playing from the MBA internal speakers until about 4 seconds later when the sound starts playing from the external speakers. I've tried plugging in earbuds that I use with my iPhone - same thing. Anyone else have this with their MBA or does the sound start playing immediately? I tried searching the forum for related issues but don't think I found anything directly related. If anyone knows of a prior post, please do include it. Thank you
