[ubuntu] Volume control not working

view story

http://ubuntuforums.org – Hi all, This is my first post :-) Before logging in, I am able to adjust the volume. However once logged in, it does not work. Rather i see the speaker and then 3 dashes "---" Please see the attachment for pic. Sound does work, and I am able to adjust the volume using the keyboard. Any suggestions?
