Has any else noticed inconsistencies with sound after 10.2.3? I have noticed that ever since I updated on my laptop, the volume up, down and mute buttons on the keyboard don't match the volume displayed in the menu bar, and to make things worse, the buttons on the keyboard typically only affect the built-in speakers, not the external speakers, which the menu bar thing changes. This is very annoying and I didn't notice it until last week.
