To find out if it's system wide or user specific, try this...
Open System Preferences>Accounts, unlock the lock, click on the little plus icon, make a new admin account, log out & into the new account.
Does Sound work in the new account?

As I posted above,this is an intermittant problem.Ergo, it does not happen all the time. I have sound now. There is no specific circumstance that brings it on as as far as I know.

Next time it happens... Open Audio Midi Setup in Applications>Utilities, see the input & output options & KHz setting there, some things will change it for their own use, then not set it back.

This still does not answer why it happens. And,as I mentioned previously,going in to Preferences/Sound and sliding the level back up solves the problem . I opened up Audio midi and it is using the built in output at 44100.Hz with a value of 0.712 and db at -10 which means very little to me. And I am not an audio idiot. Still learning about the mac after three years though.
For the record, the only audio app I've used is Garageband to record some voice overs. Other than that FCP and iMovie but not in a while. Odd,too,that I have found no one else with this issue.

Well, it was just a shot at a possibilility.
Safe Boot, (holding Shift key down at bootup), & use Disk Utility from there to Repair Permissions, trash these files...
