Hey guys, My PowerBook speakers keep clicking before a sound is played, and it's getting kind of annoying. After a few minutes of no audio what so ever, whenever something needs to make a noise, whether someone signs off iChat, or I get new mail or something, the speakers seem to initialize themselves with a little click, kind of like the sound a clock radio makes right when you turn it on. It only makes this sound if no audio has been played for a while. If I'm playing music in iTunes, everything sounds great. It's almost like the PowerBook puts the audio section of the logic board to sleep, then when it senses it has to play a sound, it wakes it up again. Is this just a problem with the Revision A Powerbooks, or is my Powerbook special? Or is there a setting or something I can turn on or off to fix this?
