Sound broken in my MacBook

I bought a new MacBook Pro installed with Leopard about a month ago. Just an hour ago, the sound went out. I have checked every setting but nothing works. I didn't change anything or do anything differently. I tried plugging in headphones and speakers - still no sound. There is just no sound coming from iTunes or the Internet. Any help would be GREATLY appreciated!

MacBook Pro, Mac OS X (10.5.1)

1. Launch Audio Midi Setup (Utilities). Make certain "Format" is set to 44100.
2. Try zapping PRAM (Hold opt cnd+RP on startup. Let go after 3 chimes).
3. Check the Sound pane of System Prefs, and make certain output isn;t muted, down, or to the wrong device.

Thanks for the reply...

1. Checked it - set to 44100.
2. Tried this but didn't seem to work, when do I hold down those commands? "cnd" is the apple key, correct?
3. Checked it - all correct.

Still not working...

As soon as you hear the first chime. Fast.

Yes, yes, of course. Just hit the "start" button, and hold down the keys, the screen will "flicker" 3 times, then let go.

It happened to me yesterday. I was using my Griffin iMic to make some voice recordings. When I went to switch back to the internal speakers and microphone they were not an option, not in the menu, just the USB iMic. I restarted and zapped the PRAM which fixed things.

I reported the incident to Apple via feedback and I recommend that you all having a similar problem also report it. Let Apple know about it officially instead of them relying on reading the forums.
