Sound and No Sound

[Michael S Peek <peek@tiem.utk.edu>]

Hello all,

I have a machine.  One user logs in (using gnome) and has sound.  The 
second user logs in (also using gnome) and does not.  When the second 
user double-clicks on the volume applet he gets the following error:

The volume control did not find any elements and/or devices to control.  
This means that either you don't have the right GStreamer plugins 
installed, or that you don't have a sound card configured.  You can 
remove the volume control from the panel by right-clicking the speaker 
icon on the panel and selecting "Remove from panel" from the menu.

Anyone have any advice on how to track down this problem?  I figure it 
has to be something in the second users' environment or dot files, but I 
haven't a clue where to start.

Thanks for your help,

Michael
