If not, you can use the "beep" program (install it with "sudo apt-get install beep", and check the manual).
But, before you try too many things, verify that you have a PC Speaker and that it is enabled, use the command amixer scontents and you should see an entry called "PC Speaker" and its playback should be enabled (i.e. Linux distros often disable the PC speaker after startup).
Why do they disable the internal speaker? It seems as if my copy of Kubuntu is very louse about restrictions... It even let's me use Linix's experimental NTFS editor:-)
Edit: I don't have internet SUDO apt-get is outside of my ability (this is why I'm considering solaris)
