no sound after jaunty upgrade

[Guy Schlosser]

Hi all, I did the upgrade to Jaunty last night, especially since it 
had been working flawlessly on my laptop.  I am having a problem 
though, I have no sound.  I asked a sighted person to look at my 
screen, and she let me know that every time I reboot, master volume 
is muted.  Even if she unmutes it, there is no sound.  I do have the 
.pulse_a11y_nostart file in my home directory.  If anyone has any 
suggestions in solving this, I would greatly appreciate the help.
Thanks much in advance,


Guy
