Trash Can is SIlent When Emptied

Turn up the volume on your machine. It must be at the lowest point currently.

Hi,
Go to system preferences / sound / and check the "play user interface sound effects"
DM

Well then, uh, did "play user interface sound effects" work?

If a simple restart of your computer does not bring back the trash sound, try booting from your install disc & run *Repair Disk* from the utility menu. To use the Install Mac OS X disc, insert the disc, and restart your computer while holding down the C key as it starts up.
Select your language.
Once on the desktop, select Utility in the menu bar.
Select Disk Utility.

Select the disk or volume in the list of disks and volumes, and then click First Aid.
Click Repair Disk.
Restart your computer when done.
