[ubuntu-za] Audacity

[simone at saxonwoldprimary.co.za]

Hi all,
I have just installed Audacity and need to make a voice recording. The  
tutorial tells me to click on a Devices tab which I don't have, all I  
have is ALSA default, under Audio I/O.
In fact several tabs are missing from my preferences menu.
What have I done wrong, and how can I fix it?
Any ideas will be welcomed.
Thanks,
Simone.
