Alum Macbook Volume spike? is this normal?

[TCU]

When I have music of some sort playing and my sound is muted, when I connect headphones and un-mute the volume, I get a split-second spike of full volume. This gets to be quite irritating and I'm wondering if there's anything I can do to fix it?.. or if its even supposed to happen?

it doesn't happen if I mute and un-mute the sound when the headphones stay plugged in.

Thanks

You can try the Sound Check in iTunes..

It's because your Mac keeps two volume profiles: one for speakers on the MacBook, and one for headphones. When you plug in the headphones and un-mute, its changing profiles, and you will hear the volume of the speakers for a split second. If you mute and un-mute while they are plugged in already, It won't do that, because the profile of volume for the headphones is still in use, until you remove them.
