Roy here I am again, yesterday when I told you I thought we solved the 
problem I was mistaken. Embarrassed I was reluctant to write you again. 
I went to discussions, Apple and found the solution, which I include 
here. It worked and I thought since you were so helpful you'd like to 
know.

  Mac OS X: No audio from certain multimedia content
	 	Last Modified on: August 11, 2006

Some audio applications may change your computer's audio settings to a 
sample rate that is too high for other applications to use. In this 
situation, system alert sounds still work, and does iTunes, but other 
applications may have no sound (audio output). This document applies to 
Mac OS X 10.3 or later and applications that use QuickTime 6 or later 
for audio, such as Safari and Quicktime Player.

This can happen on Macs that support high sample rates (higher than 
48000 Hz):
	▪ 	iMac G5
	▪ 	Mac mini (all models)
	▪ 	Power Mac G5 models that support sample rates higher than 48000 Hz
	▪ 	PowerBook G4 support sample rates higher than 48000 Hz
	▪ 	MacBook
	▪ 	MacBook Pro
	▪ 	iMac (Early 2006) and later
	▪ 	Mac Pro

For example, if you play an Internet movie in Safari, it will make no 
sound; if you open a QuickTime movie on your computer, QuickTime Player 
reports the following error (and the movie will have no audio):

  "You may experience problems playing a sound track in (Movie Name).mov 
because a software component needed by the movie could not be opened."
Solution
	1 	Open Audio MIDI Setup (/Applications/Utilities/), then check the 
Audio Output setting.
	2 	Change the Audio Output setting to 44100.0 Hz.
	3 	Quit Audio MIDI Setup.

Why does this happen?

Some third-party audio applications may change your computer's audio 
output setting. In fact, if you use the third-party application again 
after applying the above solution, the issue might occur again. Observe 
changes by watching the settings in Audio MIDI Setup before and after 
running a third-party application you suspect might be causing the 
issue. Contact the manufacturer of the application for more 
information.
