Thanks for this pointer.  I was able to figure out that it was 
defaulting to HDMI audio, which I do not have.  I DO have the external 
video attached, but VGA.  So I used the pulse audo config dialog window 
and muted the HDMI, and it switched to the internal speakers.

When I did the testing with the beta, I was not connected to the 
external video.  So that could be the difference.  Once external video 
is enabled, it ASSUMES it must be HDMI, as this Lenovo has HDMI along 
with VGA.

More testing later.  Got to run some errands.  But I got audio working.

thanks
