missing finder sound effects
first off, i posted this question before in a similar thread, but since that one was already marked as "solved", my entry seems to have gotten no attention. unfortunately, the solutions offered in that thread did not work for me, neither did i find any other helpful information through the search.
so here goes: i'm having a problem with the standard finder sounds, with things like "empty trash" or "move file" not playing. i do hear every other normal sound, like music in itunes, the error sound, the new mail notification, and so on. i have the system sounds enabled in the preferences and their volume is at max level. i tried disabling and re-enabling them, and it's no use. rebooting the system does not help either. the sounds did work for some time after i installed leopard - then they went silent all of a sudden.
what can i do? i'm at my wits end... and yes, i like the sounds, and i would really like to have them back.
