Macbook Pro 15 sound not working
I have a Macbook Pro 15" 2010, with Lion 10.7.3. As of Yesterday I have no sound! Through the internal speaker and headphone. Anybody knows how to resolve it?

Did you try different sources?
-iTunes
-Internet browser, (e.g. youtube)
-VLC player
Is the speaker icon on the menu bar greyed out? If you option+click the speaker icon on the menu bar what options do you have under 'Output device'? Which one is selected? Look into the headphone socket, can you see a red light?
SPEAKER icon NOT GREYED OUT. The selection is on Internal Speakers.
Yes I did
Click on the speaker icon on the menu bar. Does the volume control pop up? Can you adjust the volume using that control? What about the F11 and F12 keys?
Did many times. Still no sound (Headphone and Internal Speakers)
Apple store genius bar unless Zyriab can come up with a better idea (He's smarter that I am).
Ciao.

Dunno where you get that idea, lol! You've got more points than me!!! 😁
You haven't answered the question about the red light in the headphone socket. Take a look, let us know!
Sorry for the delay. I looked into the headphone socket and there is no red light!
OK, let's rule out some simple stuff first. If you click on the speaker icon on the menu bar can you move the volume control? Also, open System Preferences ➜ Sound ➜ Output, is 'mute' checked?
Speaker icon - volume control moves. Preference = Sound is not Mute. Another information: I maged to connect a USB speaker device, select the device in the Preferences ➜ Sound ➜ Output and Control the volume from the icon. But still no sound from internal Speakers and Headphone.
60Hrz, I had the same problem as you this morning but found this which worked for me

Hope you find it helps
I've had this same problem going on for awhile, and it's not an isolated incident. I've read on many, many forums of a lot of MBs having this same issue. I wish Apple would figure out a real fix and distribute it.
Apparently the headphone jack is stuck in digital/optical mode or something... I've found that I if I plug in my earbuds, open the sound preferences panel, then unplug the ear buds, it works again. Like it's resetting the digital switch in the input jack.
