Xubuntu 12.04 - sound not working

[Bill Stanley]

Hi,

As an experiment, I installed Xubuntu 12.04 to see if it is acceptable. 
  All in all, it is OK but I am getting absolutely no sound.  I read 
somewhere that XFCE and Pulse Audio might not work in certain instances. 
  I have Pulse Audio installed and I am trying to figure out what is 
wrong.  The problem can't be hardware related because my sound system 
works just fine with Ubuntu 10.10.  I also notice a lack of meaningful 
sound control programs in the default installation of Xubuntu.

I would appreciate any hints in getting my sound working.
