I've done the chrome://plugins/ with no luck.No screenshot because the message flashes on and off in a second It tells me shockwave has been disabled and highlights chrome://plugins/.
The only thing I have done and this might help. I created a "dummy" gmail account for junk stuff. It showed too much of my personal info, so I deleted it. During the deletion, it asked if I was sure I wanted to delete. Said I would lose everything associated with it.I said yes. I appears that I've lost my bookmarks, except what I imported from IE. Could that have caused this sound issue? I can't find shockwave or flash in "my programs", but the message says it's disabled.
