Thump or single drum beat sound when closing apps or alert windows
One suggested to trash the User->Library->Preferences->com.apple.systempreferences.plist.
That fixed the problem for a week but the thump or single drum beat sound has started again.
This problem started 3-4 weeks ago. I do not recall installing anything new lately.
This bugs me. I have to turn down the speaker volume. And yes the "Play user interface sound effect" box in the International Preference is NOT checked.
Does anybody recognize this?
