I don't know why but zapping the pram fixes the problem I think the correct keyword is RESETTING. I finally found an old email posting on zapping the pram that gave me the correct modifiers: Restart and hold down Option + Command + R -+ P (note NO shift key) and it worked perfect and the sound came back with a lower tone startup chime.
