I noticed that on my new 11" macbook air 2011 seems to exhibit some lag when switching over from laptop speakers to headphone. For some odd reason, when I plug in my headphones while audio is playing on my laptop, it takes almost 3 seconds to switch the audio over to my headphones. The worst part is that while it's waiting to switch over, audio is still coming out of the speaker which can be quite annoying. Anyone exhibiting the same behavior? I called Apple Support and no one could tell me if this is normal behavior.
