[Ti] Lag

[Kynan Shook]

It's a feature, not a bug.  ;-)  Fairly recent versions of OS X turn 
off the sound circuitry in order to save power in the laptops.  This 
happens after 30 seconds of no sound, and it takes 3 or 4 seconds to 
reactivate the circuitry.  Changing the volume, even if you have the 
volume feedback clicks turned off, requires turning the circuitry back 
on, hence the lag.

I can't tell you why you're having a lag with the brightness; open CPU 
Monitor or ProcessViewer and see if some application is dominating your 
computer.  Just because you aren't running any applications doesn't 
mean that there's nothing running; a normal OS X system will probably 
have about 40 or 60 processes when idle with no applications open.
