For some reason I can't hear my system sounds (like emptying the trash and the copy sound).

It doesn't work on internal and external speakers and I can still hear sound when I play a song in iTunes.

Anybody know how to fix this?

I don't know what it is, but I've go the same bug. Every now and then the system sounds will "crash." I can hear sound from itunes and dvd player, but emptying trash, ichat sounds, etc are all mute. They only way I've figured out to get them back is to reboot. Even logging out and logging back in doesn't help.

Anyone got a better solution? I'm using a 24" imac running 10.4.8

It's possible your coreaudiod daemon is crashing. Check your Console logs and see if anything is reported there. I would also check and see if you have any CoreAudio plugins that may be causing a problem. Is there any consistency to when the crashes occur?

n00b alert: where would i find console logs?

As far as I can tell, its infrequent and random. Maybe once or twice a month

Open the application /Applications/Utilities/Console to check your console log.
