Finally I found out why there was often a annoyingly long delay since 10.1.2 when using the volume key or waiting for a sound effect like emptying the trash, etc. It's because OS X turns your speakers off!! If you don't play any sounds for 30 seconds (so says the kbase article) your sound hardware goes into "low power mode" and it must be woken up.
The kbase article says that this is "to increase battery life", but lists all of the following as affected computers:
iBook (Dual USB)
iBook (Late 2001)
iBook (14.1 LCD)
PowerBook G4 (Gigabit Ethernet)
Power Mac G4 (QuickSilver 2002)
iMac (Flat Panel)
I guess by "battery life" they mean power, since Power Mac's & iMac's don't have batteries (except the clock) last time I checked.
Fortunately, some cool guy discovered this and created SoundOn (freeware) which just plays a mute sound every ten seconds to prevent the sound hardware from entering low power mode. Supposedly this will hurt battery life, but I haven't noticed a difference on my TiBook yet, and the elimination of that annoying lag is awesome!
Here's where to get it:
