Recently, the user sound effects in my Tiger have been disappearing one by one. The first to go was Volume Mount, which used to play when I moved files (it is located at /System/Library/Components/CoreAudio.component/Contents/Resources/SystemSounds/system/Volume\ Mount.aif).
I copied the component bundle from another computer running Tiger, thinking perhaps some files were missing, and replaced CoreAudio.component in the Components folder, but Volume Mount still doesn't play when I move files, and now Move to Trash, Drag to Trash, and Empty Trash don't work. Empty Trash, Poof from Dock, etc. still do. "Play user interface sound effects" is still enabled in the System Preferences. Anybody know what's going on? Thanks.
