Hi, What should I do if my sound has suddenly stopped and I can't manipulate any of the controls (in settings)? How can I get the sound back?

Check System Preferences > Sound > Output or OPTION/Alt click the sound/volume icon in the Menu Bar and tell us, what is listed and checked as Output Device.

The settings show "The selected device has no output controls" and I can't move the sound volume button (which is greyed out)

@ MacMAn45: Thanks for the tip. I did re-set the PRAM but the problem hasn't been resolved. I'm not sure what a DU permission and repair is.

Try to plug in and unplug some headphones to the front jack.
Restart Coreaudio. Open Activity Monitor in /Applications/Utilities.
Select for All Processes and search for core as seen in attachment. Then kill the process. It will restart.
Re-install the combo update over current install.
Re-install the entire OS with an "Archive and Install" Basically on Lion just run the Lion OS installer and wait 20-40 min. Re-apply all software patches.
At least some ideas.

DU repair:

Open Disk Utility and highlight drive and click to repair permissions. Then reboot to see if the audio drivers permissions may have been out of whack.

When i plug in headphones or speakers in my mac, the sound works but without, it doesn't. What Can I Do?
Remove the 3.5 mm plug you use to connect the speakers to the Mac from the Mac's audio out port, and see, if there is a red light. If so, repeatedly plug and unplug the 3.5 mm connector until the light goes away, as the red light is the indicator of the digital, optical audio out being enabled, and sometimes it just gets stuck.
