WS=> This happened to me also.  I found that the problem was caused by a 
new video card that had HDMI outputs on it.  The sound output that was 
supposed to go to the speakers went to the HDMI sound output instead.  
Check that this isn't the case and if the sound is going to the HDMI 
port, either redirect it or disable the HDMI output.
