Sounds like putting a file in the Trash, emptying the Trash, a file finishing copying, etc...randomly stop working.  In System Preferences -> Sound, the "Play user interface sound effects" box is checked.  All other sounds [watching a video, playing music through iTunes, etc...] work just fine, so it's not a hardware issue.  Restarting the computer seems to fix the issue, but then the system sounds will stop playing at some random point. 


Anyone have a solution or are experiencing this problem also?

iMac, OS X Mountain Lion (10.8.1)
